…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
