Contents
List of bug and problems[edit | edit source]
- Charge decrease as the threshold increases -> check noisy channel
- GemHit_time shows some holes -> check if it is fixed with tfine
- The reconstruction is too slow with event.C -> limited the reconstruction to the first 10k events
- The radius used on the L2 do not correspond to the real on
- µTPC disabled up to now
- Only 33% of the hits has a cluster on both sides of the L2, while in principle it should be 100% --> problem due to ROC?
- FEB from 0 to 15 are noisy at channel 62
- Peaking background on FEB=6 && channel = 62
Possible solutions to be confirmed[edit | edit source]
The charge measured with random trigger is above 10fC, up to 50 fC[edit | edit source]
This is due to few channels with very high noise:
- FEB_label = 21, chip 2, channel 3
- FEB_label = 23, chip ?, channel 26
- FEB_label = 36, chip 2, channel 3
- FEB_label = 43, chip 2, channel 45
Solved[edit | edit source]
- No signal from FEB 2 and 30 --> due to missing calibration files (raw data should be present)
