| MG1 has some issue with the HT cable (for the BT bias). There is a shortcut only under vacuum. We checked the connector but we have to do vacuum again to check it. |

Tests of Calimero time calibration with MUVI1 channel 2 (MM2)
1- channel 3 of all mates selected (see screeshots)
2- channel 1 of all mates
3- channel 1 of all mates - with channels enabled !!!!!
4- channel 1 of all mates - with channels enabled !!!!!
5- all channels telescope MM2
Number of counts = total number of counts for one channel on all mates
Conclusion :
Options to be chosen
1- with channels enabled
2- 10000 for the statistics
Remarks
To run calimero on MUVI1, caliWatcher should be set to 10202 and CaliSlave to 10223
The opposite for MUVI2, caliWatcher 10223, CaliSlave 10202 |

After disabling nptool Multithreading, online is working fine again.
Concerning Calimero, it is currently working both on MUVI1 and MUVI2 for the X at least.
Joined here is the result of Calimero for MG10C on MUVI2 channel 3 (MM7). |

|
MG9C (thin square detector coupled with thick square detector unplugged) noisy
On X channels --> no noise problem ( about 100 ORD in the dark)
On Y channels --> MATE 10 & 11 noisy ! (see picture below with noisy Y piedestals)
With internal pulser (trigered by CK_TST) the counting rate is OK only if the thresholds are set at 1 MeV. If they are set at 500 keV, the counting rate is 10 times higher than the CK_TST
For MG10C, ORD is OK ! |

Change of the HT/BT cable of MG1T (the one that had a short cut before when the chamber was closed)
MG9C is now the square detector nb 4 (Micron number) and coupled with the thick detector --> this detector was working properly
MG10C is detector nb 3 (Micron number) --> this detector was noisy before |

Test run with alpha source in front of trapezoid detectors.
First run with new LABELS updated from "MM" to "MG0" in GECO.

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

Run 30

Thresholds at 500 keV.
Run size: 1.3 G

TRIGGERS are:

Plots are now represented using the correspondance map which means that it correspond to the geometrical ordering on the detector. With this representation groups of strips missing or disfunctionning on a given region of the detector is more obvious. |

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. |
