DCal meeting - CERN Dec 16-17 th ’09 5 LPSC / J.F Muraz

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

DCal meeting - CERN Dec 16-17 th ’09 7 LPSC / J.F Muraz

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
