Numbers from Database
TEC Production Overview
(created by Marko Dragicevic, last updatet: ) (
-> 7,4 % of assembled modules are set faulty in the database at the moment
(modules not included: version > 10 and with hybrid from bad batch)

3. Numbers from Database SAMPLE for Analysis: only TEC modules
(module type: , , , , , , , , , , or )
version < 90
values from the last ARC-test
166 modules with hybrids from bad batches included
-> the sample contains 1609 modules

4. faulty modules mechanical: 46 modules ( 2,9 % of ARC-tested modules)
Dx(cut) = microns
Dy(cut) = microns
Frame Angle(Cut) = mdeg
(L. Fiore )
Current: 5 modules
( 0,3 % of ARC-tested modules)
I(450) > 10 A per sensor
(CMS Internal Note – )
number of bad channels: 24 modules
( 1,5 % of ARC-tested modules)
> 2% bad channels (Grade B >1% bad channels: 33 modules)

5. Gantry precisions 46 Modules Geometrically faulty:
Problems with database input:
The other 42 bad modules are correctly set faulty in the database.

9. Grade C – I(450) above 10 mA per Sensor
Module Test – I(450)
Grade C – I(450) above 10 mA per Sensor
faulty TEC modules with 1 Sensor: 2
faulty TEC modules with 2 Sensors: 3
(all three 2-sensor-modules contain HPK-Sensors)

10. Module Test – I(450) Missing Data:

15. Module Tests - NBadChan
Grade C - above 2% bad channels - 24 modules
Modules with 512 channels – faulty above 10 bad channels
0,78 % bad channels
Modules with 768 channels – faulty above 15 bad channels
0,28 % bad channels
In TEC there are 0,57 % bad channels till ARC-test !

18. SUMMARY assembled TEC modules according to database: 1801
(excluding 144 modules version > 90)
thereof good modules in the database:
-> overall 15,9 % faulty modules produced
excluding another 166 modules with hybrids from bad batch
-> modules left in the database:
-> thereof faulty modules:
-> around 7,4 % faulty modules
Don‘t forget: TEC has only 10 % spare !

19. CONCLUSION
We can only determine the exact quality of produced TEC modules when:
we fix all errors in the database
everyone uses the database correctly !!!
Otherwise we will not be able to foresee if we have enough material throughout the production and in the end.
