Pedestals

Pedestal 1 par 1 (all 31) : 737970

[488.4970566593083, 490.70755176613886, 478.85082127972544, 492.5306942752741, 482.2502485089463, 481.9373757455268, 465.7380475594493, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 478.8026019514636, 496.3951253808296, 482.20030007501873, 496.4514762826718, 506.88988383349465, 468.5458553791887, 477.6852634194831, 497.78751839136834]
 
Alignment to : 470.738047559

Le canal 15 ne fonctionne pas

Run de verification (737972)
- On observe un comportement bizarre sur la piste 4 , on essaie d'aligner a 450

[19, 18, 22, 18, 21, 21, 25, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 22, 16, 21, 16, 13, 26, 23, 16]

Run de verification (737973)
- Meme probleme

On prend commme piedestal 737970

Tous les canaux allumes + cable d'injection (737974)
- mean ~ 474
- RMS ~ 2.5 cx bruyants 3.3

Threshold= 474+5*3.3 ~ 491

On essaie on doit mettre 496

Si on regarde la calibration cela nous donne

VTH (mV)= (496-474)/0.1743 = 126 mV

mais la calibration n'est pas sur un canal mais sur les 2 cotes

donc seuil minimal ~ 63 mV ou fC

Pas si eloigne que ca des 50 fC prevus
