The Greek Muon Chambers (BIS)
The three Greek Laboratories:
112 (90 BIS30 +22 BIS36) chambers
ALL CHAMBERS @CERN since Sept 04• University of Athens (UoA) Tube wiring/assembly (30,000 tubes finished Dec.2003)
• National Technical University of Athens(NTUA) Quality Assurance/Quality Control of tubes (30,000 tubes finished
Mar.2004)
• University of Thessaloniki (AUTh) Chamber assembly (112 chambers finished April 2004)

…providing the servicesthe procedure
Preparation activities home(gas bars, cables +29 chambers at Thessaloniki) FINISHED summer 2004
Stage 1 (Blg 184 :equip with gas bars, FC’s, HH’s+MECCA test
78 chambers at CERN, test for gas leak OK)STARTED March 2004 - FINISHED Sept 2004 (but 7 chambers)
Stage 2 NOW HALF_FINISHED Electronic Noise test NOW
Cosmic Ray test NOW
Database NOW
Blg 283 (ALL 112 CHAMBERS) Test facilities shared with BIL team
Stage 2 (Bldg:283 started Oct 2004 after gas leak test)
Equip chambers with:
gas supply brass tubes, plugs, valves etcMezzanines boards +FC coversalignment platforms + cables + measure themHV and readout cables (stiff cables/support!!)B field platforms +cablesT sensor cablesProtective covers
A team of 2 technicians working on them since Oct Since Dec. 3 technicians + ½ physicist (since Jan.)
FINISHED 56 C
HAMBERS
RATE IS : 4 min to 5 max chambers/week Expect to fin
ish by
Easter
(Gre
ek)
…providing the servicesStage II-Blg 283 (ALL CHAMBERS)
Noise test/ Cosmic Ray Test (10 chambers before Xmas+restarted last week)
Data base
A team of 1 physicist –S.Vlachos (since Jan.) +½ physicist (Ph.D.student) (from March)
Leak test/certification
CONCLUSIONS …providing the services+commissioning the
chambers
Stage I- Blg 184 Finished 6 months ago
(but 7 chambers are still bare)Stage II-Blg 283 (ALL CHAMBERS)
Half are fully equipped, rest by May Integration has just restarted MAIN EFFORT NOW Expect to finish by July
