RUN 27 on 14th of feb.
3 alpha source (one in front of trap., one in front of square detectors)
MG10, MG4, MG7 and MG5 are OK.
MG1 shows alpha but at lower energy and with bad resolution (particularly on X). We suspect it is not well depleted. We tried to increase the bias up to 200V but did not see any change.
It is due to a non working SA/SL external cable that produces this error (we tested it with several detectors, we also tried to change the MUVI channel and it still does the same)
Conclusion :
We have tested all trapezoid detectors (MG1, MG3, MG4, MG5, MG7) the annular (MG11) and the thin square (MG10) they are all OK
Detectors (order in the GMT) :
MG10
MG1

PROBLEM ACQ , MUVI2 has no validations (DECS). MUVI1 OK!. Looks like a problem on the catchslave actor of Narval as no events seems to pass trough
The problem was caused by the cable used to triger the GMTSlave from the FanIn FanOut. |

There is a difference in angle for trapezoids -> to be investigated

|
For the mugast telescope, changing the temperature from 13deg to minus 4deg doesn't seem to have an impact as strong as for the MUST2 telescopes.
Still, the resolution improve with a lower temperature, but the improvement is of only 0.1 channel... (See joined screenshots) |
