EMB PAR, 23 nov P. Perrodo, LAPP, Annecy1 ATLAS EMB SERIE MODULE CABLING Experience started with three successive prototype modules (module 0) in 1997 Today several serie modules have been cabled. At CEA: M15,M13,M11, at LAPP: M14,M10,M12, at CERN M06. Notes written to describe the procedures: note on frame definitions (ATL-AB- EN-0013), note on cable length specifications (ATL-AL-EN-0030), note on cabling itself (ATL-AB-EN-0014), note on installing the monitoring (ATL-AB- EN-0015).

Pulse, 2. Perform TBF test, 3. Put HV Using a test bench to perform that needs to be very safe with the connectors and cleanness. Do we want that ? Electrical insulation should be checked anytime. After insertion into the cryostat and connection to the feedthrough, the 3 tests mentionned above will be performed from the base plane level (using the test bench currently at CERN for cabling) and the final HV power supplies.
