1 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).

2 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy2 Cabling conditions Work in a clean (not white) room Clean the module Inspect everything before installation Write every action in a log book max 4 people cabling at the same time check electrical insulation

3 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy3 Front Motherboards sectors 1 and 2 Cable tight, Radiation hardness Calibration cables

4 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy4 Front with temperature probe connection Calibration cables

5 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy5 Front sector 8

6 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy6 Front corner at z=3000 with patchpanel PS calibration low profiles

7 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy7 Front corner at z=3000

8 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy8 Front Patch Panel « 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.

13 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy13 Back cables properly tighten Small tights HV cables

14 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy14 Back, cables close to an external ring Cables not too close to the rings Cable tights HV cable

15 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy15 Back, temperature probe and HT protection Temp. Probe connection HV protection glued

16 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy16 Full view of a back sector Protection diodes: Remove the MB cover Some low profiles and Change the Millmax

17 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy17 Mounting the back Patch Panel

18 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy18 Back patch panel, after cabling

19 EMB PAR, 23 nov P. Perrodo, LAPP, Annecy19 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.
