Test zone in bldg.157
Barrack available
Cables exist
PC computer required:
• 3.2 GHz P4 processor
• 1 Gb RAM memory
• ~120 Gb HDD
• 3-4 PCI slots
Tasks:
• HV/LED control
• HYDRO control
• 137CS data bank
• PMT’s data bank

Modules final test with the 137Cs source (2/2 HCAL)
21.09.04 Rustem DZHELYADIN (IHEP, Protvino)
Test zone in bldg.156
Idea – not to move to b.157
• modules already on place
• exclude damage risk
• economy of manpower
14 working days truck+crane+crew
Required
• extend blue wall ~10m
• confirm space occupancy
• RP approval

Manpower for optics assembly (Romanian, Ukrainian technicians)
October-
November’04
PC-computer for final test in b.156/157, later in the pit.
Cross calibration “25 ns” LFB and LeCroy QCD’s.
?? LFB counts per 1 GeV ??
Financing from RF-I unavailable since April !!!
could postpone modules construction => April’05

Conclusions
21.09.04 Rustem DZHELYADIN (IHEP, Protvino)
Provided problems would be solved
• Construction completion by November’04 looks straightforward
• Optics assembly completion by Christmas
• Final module check (cabling, PMT+CW, rad.source test)
50% in December’2004
100% in March’2005
• Installation can start within new schedule timetable
