STATUS HIGHLIGHTS

WBS 402.1: Project Office:

We are preparing for CD-1 mini-Review in Spring 2019, planning for CD-3a in Summer 2019 and planning for CD-2/ CD-3 in Summer/Fall 2020. The dates may evolve as we learn more.

This month we have been focused on several areas in order to prepare for the CD-1 Mini-Review:

Out of the two recommendations with scheduled close in August 2018, we have closed the one requiring an update of the PHAR, and partially addressed the one requiring the allocation of sufficient expert ASIC engineering resources to meet our schedule. The CD-1 IPT Tracking Document can be found in: https://cms-docdb.cern.ch/cgi-bin/DocDB/ShowDocument?docid=13604 .

In the context of re-accessing the technical risks of the Project, we are organizing a Risk Workshop for the entire DOE scope of the Project, to take place between Sept. 4 and Sept. 13 at Fermilab, in 4 separate sessions for each L2 system. The Reviewers are colleagues mostly external to the Project. The NSF part of the Project will have a similar workshop, likely in October 2018.

We have brought on board a dedicated ESH&Q professional (TJ Sarlina) to help review the ESH and QA/QC plans, to ensure they are complete and take the lead on implementing them. We appointed TJ as our QA/QC Manager in July 2018 and, in addition, as ESH Manager in August 2018. We have rewritten our QA plan with the help of the QA professional and internally reviewed it. We had a mini-workshop on August 1 to document the QA/QC plans and ensure that all the subprojects understand what is needed and expected from them. We are in the process of collecting specific data from the subsystems on validation/ verification and calibration planning activities, in preparation for an ESH&Q Project Office initiated review expected to take place in October 2018.

We will be triggering a review of the full documentation of the Project in November 2018, in order to address the issues that our CD-1 reviewers pointed out.

We continue to flesh out the MIP Timing Detector (MTD) schedule for CD-1 mini-Review preparations. Within the US, we have filled in most of the lowest level (L4) management and we are converging on having the L2/L3 leadership in place very soon. We continue having a series of workshops to get the technical, cost, schedule and risk areas into shape. We have developed a bottom-up schedule for when the MTD will be ready for a CD-1 Directors review, and which technical decisions are necessary for it. We are aiming for a Technical Review in November 2018 and for a cost/schedule/risk review in December 2018.

Because we are now down to a single vendor for silicon for ATLAS tracker, CMS tracker, CMS endcap, a team of CERN / ATLAS / CMS experts are negotiating with the company and expect to have a site visit to Hamamatsu in late September. We will then start learning exactly when the silicon will be delivered for each subproject, and when the US will need to pay for its share. The silicon sensors for both Outer Tracker and Endcap Calorimeter are items of a CD-3a. We are collecting additional CD3-a candidate items from all L2 systems and we can firm up the CD-3a date when the international schedule is clearer.

Meanwhile, we are moving the full project towards EVMS reporting. We have defined Control Accounts and are making progress towards defining Chargeable Task Codes and Project Measurement Techniques (PMTs/EVTs); items needed in COBRA to establish the reporting. Outer Tracker and Endcap Calorimeter continue statusing their schedules, using this as an opportunity for their CAMs to understand what level of project planning is necessary to be able to collect reliable EVMS data. We have also organized EVMS training for all CAMs which has started in August and will continue through September 2018.

We had a fruitful workshop for the Endcap Timing Layer (ETL) ASIC on August 7, 2018 and we expect a follow-up workshop on September 6. In the meantime, we have reworked the ASIC schedule and integrated additional ASIC engineering resources from a University. We are also working with Lab Management on obtaining additional ASIC engineering resources and the Lab is in the process of interviewing qualified candidates.

The U.S. floats to international CMS need by dates have not changed since the July report currently the tracker subproject has the least amount of float at 7 months. The other subproject floats to iCMS need by dates are between 9-10 months, with the exception of the DAQ here there is only 5 months float, however this is by construction. The DAQ contribution is a commodity item that is bought as late as possible in order to capitalize on computing technology price/performance. We continue to monitor the floats as external deliverables / milestones are updated, or our work plan evolves.

WBS 402.2: Outer Tracker (L2 Manager: Steve Nahn, Fermilab)

One of the major U.S. deliverables for the Outer Tracker is the Macro-Pixel Sub Assemblies (MaPSAs), essentially the bump bonding of ASICs to sensors. The project considered three potential vendors for this process and has been producing dummy components for vendor qualification. On the basis of the tests of the first round of the MaPSA dummy modules received in July from two of the less expensive vendors, only two out of the three companies are retained as potential vendors (AMTec and Hamamatsu). Orders have been placed to both companies for the next set of fully functional MAPSAs.

Aerotech announced an additional delay to the delivery of the Gantry machine due a backlog of orders; the robot is now expected on Sep 5th. The items needed to complete the gantry have just arrived, so the Sept. 5 date looks firm. The delay so far does not impact our international milestones.

Tests on the functional prototype 2S module assembled at FNAL earlier this year were concluded successfully. Issues we had past month with one of the hybrids not responding were addressed by protecting better the module from light in a well-sealed box.

Details

Sensors 402.2.3

402.2.3.1 Sensor QC Centers

Brown measured diode characteristics to understand effect of connecting them to 10x2 flutes of probe pads. There are some disagreements with measurements at Vienna and we are investigating.

Brown designed and ordered a new PCB for the probecard to contact the process QC flutes. Connectors have a long lead time - 14 weeks. Designed holder to mount probe card on probe station.

Brown and Rochester compared test results for some old ST sensors. There is broad agreement in the observed trends but there are some differences in the details of the measurements which we are investigating.

402.2.3.2 PS-P Sensors

Prototype

Brown received prototypes from Novati/NHanced

402.2.3.3 PS-S Sensors

Prototype

Brown received prototypes from Novati/NHanced

Electronics 402.2.4

402.2.4.1 MaPSA

Prototype

Dummy MAPSA parts have been received and tested at Fermilab. Parts with underfill have unacceptable bow. The current underfill uses a heat cure. We are now obtaining underfill material which has a better thermal expansion match to silicon and has a room temperature cure.

Parts from two assemblers, I3 and AEMtec, were tested. The I3 parts had low bump yield, especially the parts with underfill. AEMTec parts look better and have good bump connectivity. As a result of these tests, and increased quotes from I3, we are dropping I3 as a vendor and will have the next set of parts assembled by AEMtec and Hamamatsu. Hamamatsu will also be fabricating the sensor components.

Orders are being placed for the next round of prototypes, which will include the first fully functional MAPSA assemblies.

402.2.4.2 Test Systems

Hybrids

Nothing yet from iCMS side.

Module

2xSSA module components are in hand (PCB and interposers), assembly will start next week. DAQ (firmware and Ph2DAQ) for the 2xSSA module is ready.

Software for the cold box slow control is almost done. Minor tweaks in the design are ongoing based on the prototype experience.

MaPSA

Final version of interface board in hand. Final version of probe card still needs to be designed.

Modules 402.2.5

402.2.5.1 Module Assembly Consortia

East Coast

Brown: The cleanroom on the 7th floor of the Barus and Holley building is being retrofitted for module assembly use.

Rutgers: hired a person to supervise the clean room, so theres been a lot of set-up work

on room layouts, fixtures, equipment calibrations, etc.

Fermilab

Aerotech announced yet a third delay for the gantry robot, now indicating that it will ship on September 5. The problem is a backlog of critical components from a third party. Even if they do ship on the 5th this will make it difficult to have gantry ready for a demonstration during the Modules workshop at the end of September.

Infrastructure

FNAL: Components for a gantry-based readout hybrid gluing fixture are being machined at MAB. A design for 2S bias tab and kapton insulation fixture is nearly complete. We will initially fabricate two of these - one for the Brown group and one for us. An order has been placed for 20 2S carrier plates. Our lead engineer, Greg Derylo, has been contributing to the design of the plate as they will also be used in the burn-in system, which he is also designing in part. A coupling plate for the encapsulating robot in Lab D was fabricated this period. Steel inserts for top and bottom 2S bonding jigs, initially fabricated at Wayne State, are being machined in the Village machine shop, and the jigs will be sent to Princeton once they are complete.

402.2.5.2 Module Components

Hybrids

We dont expect to receive CBC3 hybrids until next year and at FNAL we are producing stiffeners for these hybrids (see below).

Mechanics

Brown: PS module assembly jigs have been modified to incorporate more assembly steps into fewer jigs. This will also improve the repeatability of assembly by removing some of the more manual steps. New jigs with these modifications are in progress at Brown's machine shop.

Brown: A second iteration of a PS module carrier design has been fabricated. This includes all the components for shipping two PS modules on one carrier. This prototype will be used with dummy PS modules to further iterate on the PS module carrier design.

FNAL: Work has started on machining 180 sets of 2S stiffeners in response to a request from the CERN group. The layups of the K13D2U carbon fiber prepreg were done at both FNAL and Purdue, with the Purdue layups still in progress. Purdue recently completed measurements of the K13D2U thermal conductivity and these will be included in a CMS Detector Note that Stephanie Timpone initiated at the beginning of the summer.

402.2.5.3 Module Assembly

PS Modules

PS Prototype

1. Brown: The new wire bondable PS module, PW1803, has been through additional rounds of inspection and will be shipped to Princeton for bond testing, programming, and evaluation of a new wedge bonding tool. This module also has more realistic readout hybrids, allowing for a more accurate bonding experience.

1. Princeton: The wire Bonding stage for the PS module is complete; alsosuccessful bonding of the first mechanical model PW-1802 PS module

1. FNAL: Arnab Ghosh has completed layouts for dummy PS sensors to be laser diced from 150mm blank silicon wafers.

. 2S Modules

2. 2S Prototype

1. Brown: SA1804, a dummy 2S module, has had more realistic flex hybrids placed using a modified jig. After inspecting the module for alignment of hybrids to silicon and checking for condition issues, it was sent to Princeton for bonding practice, fixture design, and programming.

1. Rutgers: encapsulation studies are converging, we should be ready to pot a dummy module by the end of the month.

1. FNAL: We are joined this month by a new RA, Fabio Ravera, and relocating the module test system from FCC to SiDet has allowed Lorenzo and Fabio to read both the left and right hybrids on our first functional 2S module for the first time.

WBS 402.4: Endcap Calorimeter (L2 Manager: Jeremy Mans, U. of Minnesota)

The endcap calorimeter full-silicon mockup cassette has been assembled and successfully tested. The measured temperature distributions show good agreement with simulation, and the performance of the PCB-based baseplates has been confirmed in the mockup cassette. This technology will be considered the baseline, and studies are underway to leverage the PCB design to reduce noise sensitivity in the detector. The thermal performance of the scintillator tileboard thermal mockup has also been demonstrated, and the observed temperature distributions meet the requirements for silicon photomultiplier cooling after addition of thermal interface pads. A development board for the slow-control chip has been produced, to provide a path to make progress on module electronics in advance of the international first digital version of the Endcap Calorimeter readout chip being available. The Endcap Calorimeter readout chip and the Concentrator ASIC remain on schedule. We have finalized the conceptual design of the Concentrator ASICs trigger path first prototype, and presented it to the ASIC PMG on August 20, 2018.

Details:

Silicon Sensors, and Silicon Modules:

TTU fabricated additional mockup silicon modules so we could test a variety of baseplate materials: PCB (5), carbon fiber (5), and copper/tungsten (2). These were all thermally cycled (-30 to 30 C) modules at TTU before shipping to Fermilab, and at Fermilab to investigate the degree of warpage and mechanical stability. Fermilab performed mechanical and thermal FEA calculations on modules with these various baseplates, and these simulations showed good agreement with measured mechanical (physical deflection) and thermal measurements. TTU and CMU ordered the needed wire bonders in preparation ahead of modules that will be needed for prototype 1. The group completed neutron irradiation of test samples at Brown and UC-Davis, and the IV/CV and TCT measurements are now ongoing with some results to be shown at UCSB module workshop that will take place at the end of August.

Scintillator, and Scintillator Tile-modules:

We have been working on defining the decision criteria for making the baseline scintillator choice including consideration of blue vs. green scintillators. We continue to develop a slow controls test system, and we are working with the international CMS TCDS group on fast controls specification.

Cassette:

We performed cold testing of all-silicon mockup cassette with new modules with various baseplates. We measured module warping with a CMM, and compared the results to FEA studies that our group has done. We also measured with a CMM the CTE of baseplates made of various materials, and also compared with FEA calculations. We designed a PCB baseplate with electrical shielding layers, and worked on the design of the cassette mounting scheme into the absorber.

ECON:

The organization of the lpGBT design transfer is in progress. Fermilab engineers have scheduled a trip to CERN for lpGBT design meeting on Sep 24-28. G Deptuch and J Hirschauer have finalized the conceptual design of the ECON-TRG prototype 1 and presented it to the ASIC PMG on Aug 20.

Project:

The project team is continuing to work on some issues raised at the CD1 DOE IPR review in June. We are implementing our revised plan in the Resource Loaded Schedule to take into account a 5-6 month delay in the next HGCROC submission, by planning for a faster production schedule for the modules and cassettes. We had started to plan for deliverables and goals for a new Major System Prototype 0, between the mockups and Prototype 1, so the needed designs, prototyping, and tests can be done prior to a CD-2 review. However, since the CD-2 review is now pushed back to late-2020, this additional prototype 0 is now no longer necessary. Due to the delay caused by international CMS revisiting the scintillator tile-module geometry, the mixed cassette mockup deliverable is also delayed. Work for the mixed mockup cassette is needed ahead of prototype 1. We are reviewing a revised schedule for the mixed mockup cassette. We are also reviewing our risk register to ensure it is updated with the new plan of having a faster module and cassette production schedule. We have been determining possible deliverables for CD-3a: production sensors, and production wrapped scintillator tiles.

Other:

We have no changes at this time for the subproject float to need-by dates. We have no updates for the risk registry or the IPT tracking registry.

WBS 402.6: Trigger/DAQ (L2 Manager: Jeff Berryhill, Fermilab)

The Trigger/DAQ activities during the past month (August 2018) focused on finalizing the design of the initial prototype of an Advanced Processor development trigger board (APd1) and on developing algorithms related to calorimeter-only Jets/MET/HT triggers as well as track-matched muons, forward electrons, and particle-flow taus. A first implementation of the particle flow and pile-up mitigation algorithms for the Correlator Trigger was demonstrated this month on Amazon Web Services (AWS) FPGA instances. We have also met the August milestone for emulating the e/gamma performance. The project expects to complete the APd1 design milestone by the end of August, and is on track to complete the APd1 produced milestone this Autumn. Finally, the project is on target to complete the Jets/MET/HT algorithm milestone in October.

Details:

L1 Trigger Hardware:

The layouts of the APd1 and its Rear Transition Module (RTM) PCBs are nearing completion with the last few routes being optimized and the overall routing being reviewed, and parts are being ordered. We have 9 Rev B IPMCs in our testing lab now, with the first one of them fully checked out prior to authorizing the assembler to run the remaining 8 PCBs. Firmware development continues on the UW-IPMC (ZYNQ-7000 based processor mezzanine to provide Linux-based control), and the PO for Rev B UW-IPMC PCB has been issued for 25 units of which we will initially assemble 20.

L1 Calorimeter Trigger algorithms:

The GCT algorithm, which completes clustering started in the RCT-level and classifies them as electromagnetic or hadronic in origin, has been reimplemented learning from the initial version to optimize multiple levels of loops. The change was necessary to cope with changes in the Xilinx Vivado HLS package. The new code meets the timing requirement. A reduced version is ready for testing on the CTP7 test stand at CERN. The classification process is followed by identification of highest transverse energy objects, electron/photons, taus, jets, sum of higher transverse energy objects (HT) and energy imbalance in transverse plane (MET) based on calorimeter information only. Note that the RCT code, which does initial stages of clustering without sharing across the boards, has been completed and tested. Further improvements to edges of the geometric acceptance of the cards is underway.

L1 Correlator Trigger algorithms:

Studies updating the particle flow algorithm resource usage with the latest version of Xilinx Vivado HLS found an optimization for higher logic resource usage than previous versions. The follow-up action item is to study how to improve resource control in HLS. A first implementation of the particle flow and puppi algorithms on Amazon Web Services (AWS) FPGA instances was demonstrated. The AWS demonstration has lower prototyping costs and includes examples on how to interface with the cloud FPGA instances. A study of the vertex finding matching window effect on the particle flow + puppi HT calculation found an optimal window around 0.5 cm. Progress continues on the track-muon linking demonstrator including a displaced muon algorithm with track-unmatched muons. Input injectors for the demonstrator are complete and firmware (HLS) algorithms of both track propagation and track matching have been developed and are in testing. A first comparison of standalone tau identification algorithms (hadron-plus-strips) against tau identification with particle flow inputs was performed. Similar performance is achieved except in the 3-prong tau case where particle flow shows an inefficiency. The follow-up action item is further investigation into collimated charged hadron efficiencies. Particle flow taus are natively implemented in the endcap while work is in progress for the standalone tau algorithms. First studies of the HGCal trigger inputs to the correlator are studied for electron identification in order to improve performance and a first study of multivariate classifiers was presented. Performance studies of the current particle flow electron identification algorithm over all eta was performed showing 20-30% efficiency loss due to lost tracks from the input tracking trigger. Currently this is recovered with standalone calorimeter algorithms but loosening track requirements and bremsstrahlung recovery has been identified as next steps.

Milestones Progress for 2018:

Milestone: Emulated performance and efficiency for Jets/MET/HT, October 2018

Progress since last report: The GCT algorithm, which completes clustering started in the RCT-level and classifies them as electromagnetic or hadronic in origin, meets the timing requirement and a reduced version is ready for testing on the CTP7 test stand at CERN. The classification process is followed by identification of highest transverse energy objects, electron/photons, taus, jets, sum of higher transverse energy objects (HT) and energy imbalance in transverse plane (MET) based on calorimeter information only. The project is on target to complete this milestone on time for both the standalone calorimeter trigger and the correlator trigger algorithms.

Milestone: Design complete for APD1 board, July 2018

Progress since last report: The layouts of the APd1 and its Rear Transition Module (RTM) PCBs are nearing completion with the last few routes being optimized and the overall routing being reviewed, and parts are being ordered.

Milestone: APd1 Produced, 30 September 2018:

Progress: Wisconsin have 9 Rev B IPMCs in their testing lab now, with the first one of them fully checked out prior to authorizing the assembler to run the remaining 8 PCBs. Firmware development continues on the UW-IPMC (ZYNQ-7000 based processor mezzanine to provide Linux-based control), and the PO for Rev B UW-IPMC PCB has been issued for 25 units of which we will initially assemble 20.

WBS 402.8: MIP Timing Detector (Acting L2 Manager: Chris Neu, U. of Virginia)

The MTD continues to progress in its technical areas as well in the areas pointed out to be lacking during the June 2018 CD-1 IPR Review.

Several technical milestones have been achieved on schedule: e.g. the specification for the BTL Concentrator Card was finalized, a decision was taken on the power provision to the BTL, the procedures for BTL assembly of trays and ETL assembly of modules have matured significantly and agreed upon by the international collaboration, etc.

The WBS structure and organization chart have been updated and refined to reflect the increased clarity in the areas of activity. Preliminary versions of BoEs for every L4 area have been collected and the process of building scenarios for the scope of US-MTD deliverables has begun.

The outline for the CDR document has been updated to reflect the project organization and areas of activity within the US. Overall co-editors for the CDR have been identified and weekly meetings with the content providers have begun.

A Cost/Schedule/Risk Workshop was held at CERN 23-24 August. Risks for all L4 areas have been enumerated and the process of entering these into the Risk Register has begun. Risk mitigation strategies continue to be pursued, including the feasibility and cost impact of an optimized redesign of the ETL.

We are preparing for a Technical Review in mid-November 2018 and for a Cost/Schedule/Risk Review in mid-December 2018.

Details:

The MTD project 402.8 has made significant progress in the last month. The most important task at this time is the definition of the US scope. Input to this decision is cost, schedule and risk evaluations from every L4 activity area. L4 managers have been working on gathering this information for the last 8 weeks. This has culminated in the collection of preliminary BoEs for every activity area, a major milestone.

With this information in hand Frank Chlebana, Chris Neu and Jeff Spalding are working on building different scenarios for the US MTD scope. Given funding constraints, not every L4 activity area will necessarily by part of the ultimate suite of deliverables provided by the US. All US stakeholder institutes are represented in this exercise, and the US MTD community understands the constraints. A US MTD All-Hands meeting will be held Sept 5-6 at FNAL where a proposal will be defined for the US scope. This proposal will subsequently be presented to the USCMS HL-LHC Advisory Board (Max Chertok, chair), interior to which a dedicated MTD advisory sub-committee has been formed. The final definition of the US MTD scope is expected by mid-October.

Other aspects of the requisite documentation are maturing as well. Risks for each L4 activity area have been enumerated and the process of formalizing these risks in the Risk Register has begun. Developing the RLS in P6 has started with the major internal and external milestones; now with the preliminary BoEs in hand, the plan is for every L4 manager to work with Lucas Taylor, Bill Freeman and Chris Neu to enter their activities into P6. A series of dedicated P6 workdays are planned for the next two weeks. We expect to have first full versions of BoEs, RLS in P6 and risks formalized in the RR by the end of September. We expect subsequent iterations as our scope comes into better focus, but we are on track to have full versions frozen and ready in advance of the OPSS Cost/Schedule/Risk Review, scheduled for mid-December.

The CDR document is maturing in parallel to all of the activities described above. A re-organization of the document has been completed and content contributors have been defined for every subsection. Two overall co-editors (Lothar Bauerdick and Toyoko Orimoto) have been identified. The co-editors have instituted weekly meetings among the content contributors to discuss and present progress; the associated milestone is to have v0 of the CDR distributed to the US MTD community for comments by 1 October. A subsequent v1 will be prepared by 1 November, two weeks before the MTD Technical Review, scheduled for mid-November.

Several key technical milestones have been achieved on schedule. The specification for the BTL Concentrator Card (402.8.3.3) was finalized, allowing for an accurate costing exercise for this component. An important point was the settling of the issue of the power provision to the BTL SiPMs, which will be handled through the BTL FE board, a non-US deliverable. Also, clarification was received from the international MTD project on the requirements for the materials for on-detector PCBs. The procedures for both the BTL assembly of trays (402.8.3.4) and ETL assembly of modules (402.8.4.4) have matured significantly in the last 4 weeks and working versions of these models, developed by key US leaders in this effort (Adi Bornheim and David Stuart) and agreed by the international project, are now in hand.

The issue of risk mitigation in the ETL continues to progress. In the reference design for ETL, the highest risk exposure areas are (1) the potential for additional engineering design cycles and engineering labor associated with a design that meets the stringent time resolution requirement of the FE ASIC and (2) the possibility of low wafer yield of functional large-size LGAD sensors. It was shown that in an optimized redesign of the ETL with smaller sensors, the per-wafer silicon use-efficiency increases by a large amount hence reducing the exposure to cost risk due to wafer losses. However, the smaller sensors introduce additional inter-sensor gaps, requiring a second measurement layer to maintain high per-track efficiency. Such a 2-measurement design would not only preserve efficiency but also help mitigate the risk associated with the FE ASIC, since in such a design the ASIC time resolution specification is relaxed, which lessens the demand on the engineering. Further, a small-sensor 2-measurement ETL would allow for continuing and deepening our collaboration with the ATLAS HGTD group on sensors and FE ASIC. An important final point: It was shown in the MTD General Meeting on 24 August that the silicon sensor cost for such a design would be within 5% of that of the current reference design, mostly due to more effective wafer utilization and sensor placement optimization. Further studies continue on the cost implications on other system aspects, as well as the feasibility in terms of provision of services and cooling for such a design. A decision on the viability of the redesigned small-sensor 2-measurement ETL is expected in early October, involving the international MTD project and international CMS.

We have to wait for the cost and schedule information to be assembled and evaluated before we can decide if the MTD can be ready for baselining together with the rest of the Project in 2020.

ISSUES

Major issues are to bring the MTD up to a CD-1 level of maturity, to fully define the US scope for the MTD, and to ensure the overall project fits within the DOE funding profile.

We continue to address the comments and recommendations of the June IPR and to raise issues to Lab management with respect to procurement resources, ASIC engineering resources, the need of an irradiation facility, etc. Weekly meetings between the project and the procurement department are continuing. They have succeeded in moving procurements along and have helped the procurement department understand the needs of the project. Monthly ASIC PMGs are continuing as well. The project manager and relevant managers for the HL-LHC CMS ASICs attend these monthly PMGs. For the irradiation facility, the project is getting regular updates from lab management. After discussions between Lab Management and the stakeholders an official proposal for an Irradiation Test Area ITA at the end of the Linac has been submitted to the Lab Management on August 20, 2018.

Within international CMS, the current need by dates leave roughly on average about 9 months of float, which is small compared to the size of the project. We monitor these dates monthly (see the beginning of the report).

We have assigned people responsible for all items in the IPT tracking document and will be reporting on them as we update the schedule or close them out. Twenty-one of the recommendations are expected to be closed before the for the CD-1 mini-review. We have closed one of them this month. Table 3 below summarize the IPT tracking areas, breaking them down by scheduled close dates on the left, and breaking them down by responsible people on the right. We will be updating these tables each month.

COST AND SCHEDULE SUMMARY

The financial status (DOE part only) is shown in Table 4.

The DOE OPC table contains the first $500k that was reprogrammed from operations during CY16 and the second $4M which arrived in FY17. Note that the small amount in the FPIX row is for work performed at Fermilab for FPIX and should be reimbursed by Cornell / NSF. We are still missing $564k funding from DOE to receive our full $12M funding for FY18 (see last line of table).

In the meantime, on June 14, 2018 we received a revised profile for the out-years under the assumption that the House and Senate marks will be confirmed in the final FY19 appropriation. By the mini-review the goal would be to fit within this profile.

For the time being we are updating two different cost rollup spreadsheets using the two different guidance/profiles.

We continue to refine the cost estimate of the MIP Timing Detector. Our current plan is to keep our contribution to the MTD to $12M (fully loaded) in order to stay within the overall cost envelope. We have been holding a series of workshops and meetings to get a crisper cost estimate and profile in order to define the US MTD deliverables in this cost envelop scenario. We expect to reach a decision on the US scope in October 2018. In the meantime we will continue compiling profiles with and without the MTD detector as it cost matures in order to assess the level of contingency and risk to the Project completion.
