BarrelBarrel in truck position in pitInfrastructure installation finishedElectronics installation delayed by availability of componentsLV PS:

Delays from manufacturer (MDI)First two proto failed load test (failing SMD capacitor)

FEB: QPLL problem solved but still OTx problems6 month delay: half should be recovered by new production/testing scheduleAll barrel FEBs by August (EC FEBs by November)

Goal: install all electronics before moving to the IP?Cool down in IP:

Start of cool down on 22/11/05Barrel cold (will take 6 weeks) by end of December 2005LArg filling beginning of Jan ‘06Cryo ready for cold tests by mid JanThen cold forever…

Endcap C: cold test resultsCold test successfully performedElectromagnetic (EMEC):

6/31872 (0.19‰) dead channels: 5 EMEC (3 strips, 2 back) + 1 PS16 HV problems (1408 lines):

13 sectors can be biased only on half of the semi-gaps (can be corrected SW: no acceptance loss)2 sectors shorted together along η1 sector problems on both sides (∆ηx∆φ=0.2x0.2) at η=2.3 (0.2%): could be operated at ~500V (half nominal voltage)

Hadronic Endcap (HEC):2/3072 dead channels (0.65‰)

Forward (FCAL):11 shorts (0.19%)

Iseg HV modulesHW responsibility: CERN, KTH, WüppertalModules still unstableDuring barrel cold test (August 2004) about half of the modules failed in going to 2kV:

Problem traced to a bad batch of 10 nF/3 kV filter capacitorscapacitors

Capacitors replaced on all modulesDuring Endcap C cold test (February ‘05) still several failures at V>2300 Volts:

Failure of the voltage regulatorTask force in action to investigate the problem and interact with the company:

Three Milano people involvedMeeting at CERN last week (also with Iseg people)


Iseg HV modulesTests performed in Milano, CERN, IsegWe built 8 load boxes (32 channels each) to do a systematic qualifying test of all modules at CERN:

1.5 µF and 150 kΩ in series on each channel to mimic a typical calorimeter HV channelLong duration testsBoxes at CERN since last week

Iseg examined defective modules:opto-coupler failure in the regulation circuitryopto-coupler replaced (3 kV→7 kV) on 30 modulesBut origin of fault not fully understood

New modules at CERN since May 9:Modules under test w/ and w/o load boxes at maximum voltage (2500 V)So far so good

Unforeseen and very urgent activity
