Cosmic test bench
2 SM can be sitted side by side for
combined Assembly / Calibration

Crating & ShippingProcedure for: Loading at Grenoble, shipping, customs, unloading at
CERN are validated and can be re-used for DCal SM

ScheduleAssembly, test and calibration for 1 SM: (based on 3 SM
experience)(under the hypothesis that the stripmodule are fully equipped (LED, APD etc …)
Strip delivery + first LED test (standalone) : 3 days (1 day / 1/3) Cabling : 3 days (1 day / 1/3)
LED driver system + fiber assembly : 1 day Electronics assembly and test : ~ 3 days Calibration measurement :
• 3 passes / 1/3rd 9 days
4 weeks minimum are required to assemble and calibrate a full Supermodule
Manpower (FTE): 1 Eng. + 2 Tech. + 4 physicists

DCal meeting - CERN Dec 16-17 th ’09 8 LPSC / J.F Muraz
- Assembly, cabling, calibration and shipping of DCal SModules
- Management of all DCal SM cables production at Grenoble.
- Production of strap foils for 2 (or more) DCal SM.
If green light from IN2P3. If no impact on EMCal schedule. If manpower support from D-Cal contributors. (SM Calibration)
More platforms must be produced to store EMCal-DCal SM @ Grenoble
Grenoble possible contribution to D-Cal

Cosmics calibration
Test and calibration : Fix any hardware problems (LED, ADPs, cabling,
electronics …) Adjust the APD gain on the overall SM Calibration performed by 1/3rd of SM 3 passes required to achieve < 3% dispersion
(starting from 15%). 16 hours/pass (200 to 500 muons / tower
required
~15%
~2.3%
