Both HCAL half-barrels are complete and in their alcove

positions at the CMS hall.

Starting in Autumn 03, electronics will be installed.

After a burn-in period, vertical slice operations will begin and continue until the

CMS magnet test in late 2005.

HCAL Completion and M&O HCAL Completion and M&O HCAL Completion and M&O HCAL Completion and M&O • HCAL Deliverables are stand-alone working calorimeter

modules (HB+, HB-, HE+, HE-, HF+, HF-, 5 units of HO) that are installed and cabled up, but not operating in an integrated manner. This will be done by early ’04.

• Delivery includes HPD’s, Electronics (FE/TRIDAS) and Optical Links from Detectors to Underground Counting Room

• Test beam calibration (’02, ‘03) is NOT M&O• Spares and components needed to keep HCAL operational

are NOT M&O.• There is a vertical slice operations period before installation

underground. This is a period of M&O • Test beam studies called for by operational experience IS

M&O (’04 onward)• Technicians and engineers required to keep an operating

sub-component of HCAL operating (independent of when) ARE M&O

• Physics and simulation software development, calibration data base maintenance IS M&O

RBX StatusRBX StatusRBX StatusRBX Status

• Efforts in the previous calendar year have been dominated by preparations for test beam.

• The RBX’s house RMs which contain photodetectors (HPD’s for HB and HE), the Front End electronics and Optical Links all in a single Unit. They also house LV/HV Units, Calibration Units and Control Modules.

• The HB RBX’s are complete, except for

• Need to complete cooling channels for full RM production (for 160 units)

• Need CCM (40 units)

• Need Calibration modules (40 units)

• Need LV modules (40 units)

• Services/integration items

• The HE RBX’s are complete except for the items above

• The HO RBX design is being finalized (including RM’s)

R&D phase over except for

Understanding a few odd-acting tubes:

Continuing lifetime tests under several different HV conditions Understanding the test beam data from last summer Irradiation of selected tubes

Status:

• Of the 88 still in house, 32 are fully tested, but not yet graded

• The 56 left are mostly tested.

• We have accepted 92 and rejected 22 (which have been returned)

• We have 22 in standby (small discrepancies or odd behavior)

The best guess for yield is therefore 114/136 = 84%, since the standby category would have technically met our contractual specifications.

• Out of 224 production tubes at UMN, 136 have been fully tested/graded

1. Steady Progress

QIE development/bench studies – began 1999

2. Front-end electronics are on schedule

Very little schedule float for GOL

Infrastructure at SX5 for burn-in and slice tests must be provided

200 Pre-prod cards have been built Feb/Mar’03

3. Ramping up the nested production, test and assembly lines for readout modules

4. Complete analysis of board level radiation testing

5. Full Production to start July/Aug. ‘03

6. Development of a low-noise cable and connector configuration for the HF photomultipliers

HCAL CalibrationHCAL CalibrationHCAL CalibrationHCAL Calibration

Goal: Calibrate from test beam to 3 TeV. Time HCAL electronics.

Monitor performance, including radiation damage.Tools: 1. Nitrogen laser distributed to each sub-detector.

Excites scintillator 2. Laser injects light to photo-detectors.

3. LEDs (fast) inject light to photodetector. Programmable pulser.

4. Moving wire radioactive source for long term calibration.

5. Charge injection to ADC’s (QIE).Specialized calibration modules designed and built to achieve

goals.

HCAL DCS StatusHCAL DCS StatusHCAL DCS StatusHCAL DCS Status

DCS is the Detector Control System. It monitors the Detector and performs what used to be called “Slow controls”

The low level servers of HCAL control subsystems are almost ready.

All defined server prototypes tested during beam-test in June-September of 2002. Bugs found and fixed.

HCAL is in the vanguard of DCS on CMS


HF statusHF statusHF statusHF status

The HF is a diversified project consisting of contributions from many nations as well as CERN.

All detector mechanical components (wedges, strongbacks, backplanes) have been delivered ahead of schedule and are at CERN.

Production of HF tables is well advanced: for the first one, the welding and thermal treatment is done and is being machined now, for the second, the welding is complete.

Production of the support outer shield has started for the first HF. Contracts for machining placed. Expect delivery of first table+shields at end of September 03. Second set by spring 2004.

All PMTs have been delivered to IOWA and testing is >90% complete

85% of quartz fibers have been delivered to CERN and are being cleaved and bundled in Hungary

21/36 wedges will be completed in May ‘03
