EMB PAR, 23 nov. 2001 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). Slide 2 EMB PAR, 23

Colonettes : Great care to screw them on the patch-panel.
Connection to the pig-tails is very delicate. Some work has to be
done to secure it, particularly in the final cryostat. Slide 9 EMB

Electrical tests in building 180 After half-barrel rotation (z axis
horizontal, outside the cryostat): it is possible on each
half-module (32) to: 1. 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.
