Summary of EMCal SM #1&2 Installation (September, T. Awes)
January 30, 2009 -- Super Modules at Point-2
February 2 – 13, 2009 – Super Module Integrated System testing at CERN
February 16, 2009 -- Ready for Installation
We are still on this schedule.. (details in a few slides)
Since last update (Sep) : Overview• EMCAL TDR presented at LHCC meeting Sept. 23-24• DOE review at LBL (Berkeley) Oct. 16-17• StripModule production underway in US and EU. US SuperModule assembly/calibration operation moved from Yale to WSU (Detroit). • FEE components produced (FEC, T-card, IPCB, GTL,..)
Examples of past delays/issues – all dealt with.. :• Materials procurement for EU modules• SuperModule crate shipment to US• Counterfeit voltage reference for FEE card from electronics broker..• Issues with APD characteristics (worse gain)

18 of 20 produced (24 needed) ready for installation in SM#1 Crate
Cosmic Ray testing of StripModules in progress – final cosmic ray calibration awaits integration in SM Crate
Ready for SM Crate Delivery on Nov 19
Breaking news (~12 h ago):Delivered SM Crate has “visible damage”.Impact on schedule if the damage can be repaired locally: +2 days.If not (maximum impact; instead use US SM#2 crate - from Geneva Nov 22): +5 days
US SM#1 from Oct 17 to installation window

SM Mechanical Assembly Start Delayed Nov 10 to Nov 19
Currently plan: Add assembly labor by stopping SM#2 module production hold Jan 23 CERN arrival date
EU Assembly Status• 5 Module assembling stations in full operation (2 LNF, 2 Catania, 1 Nantes) : 128 Modules assembled so far (44% of 1 SM) Rate 25 module/weekEnd of module assembly before Mid January
• WLS fiber station in operation at Frascati : 1100 produced so far (95 % of 1 SM)
• Gluing (Light Guide – APD) station in operation at Catania: 300/week. End of gluing in Mid December
• APD test station in Catania:Mission accomplished (100% of 1 SM)
• Strip Module assembly:Started this week in FrascatiRate = 1 Strip Module/Day when modules/parts are available
• SuperModule (SM) assembly:Insertion of Strip Modules in the SM Crate will start next week in GrenobleCosmic test bench ready to run
EU Part Delivery Status
Most of the parts for the EU SM have been delivered apart:• Last batch of Lead Tiles (80 modules) by end of November• Last batch of Straps (50 modules) in December• Last batch of Scintillators Tiles (110 modules) : produced but still on the difficult way from Russia• Strong Back (about a half) by end of November• Components for the SM crate : Cable fixation, Shims, LED box• Electronics : FEE crate and cards, LED system
For the installation: • Carriage assembly on the way for 1 SuperModule• Insertion tooling almost ready for use
APD/Module/Stripmodule/SM database in progress
Completion of EU SM still expected by end of January

EMCal Electronics• EMCal readout infrastructure fully installed in L3 and on CalFrame
• Connections not quite complete• EMCal readout chain fully designed, prototyped, and tested @ CERN PS and SPS in 2007• APD + preamplifiers received for first 2 SM
• Assembly and Testing at Catania and Houston• EMCal PCBs and components:
• T-card, IPCB, GTL, FEE orders placed (Sept-Oct). All items received for first 2 SM, except FEC (under testing; enough for WSU in hand, for Grenoble expected tomorrow), and GTL (expected tomorrow).
• Trigger: TRU and STU prototypes – ongoing work • LED System: Final design being completed
• Prototype available initially for SM assembly sites.• EMCal FEE crate design complete, first two shipped to US, two more (for Grenoble) in production.• Expect to have full FEE crate readout of first 2 SMs ready and operational at SM assembly sites by late November/early December. - Need two more RCUs for Grenoble..

Summary Trigger Unit
TRU and STU
• Prototypes exist• Trigger meeting ongoing today• Intense TRU development period (Hans M., Dong W.,
Jo S., Norbert N.,..) • STU development (Olivier B.), incl. communications
with TRU; following ALICE standards (help from Anton J., Pierre VV. appreciated)
Summary• Module assembly well underway at WSU and in EU.
• Readout Electronics deliveries soon complete.
• LED Calibration system being finalized.
• TRU+STU prototypes completed and being tested.
• Facilities and infrastructure upgrades at SM assembly sites completed, FEE readout+DAQ operating.
• Insertion tooling is ready and tested.
• Production meeting at WSU/Detroit, Dec 1-2
Schedule is tight..
Extra
APD+Preamplifier Assembly & Test
• Assembly and test procedure – Assign serial numbers– Measure gain vs bias, temperature dependence– Record in database– Sort according to performance– Attach Light-guide and housing
• Results of measurements of first 500+ APDs @Catania:
V(Gain=30)Catania
V(Gain=50)Hamamatsu
Significantly more APDs with V30>400 V than expected in later batches.. Problem for equalizing at desired gain.
