This pedestal run was done as a reference, the pedestal were also saved using das and are exactly the same as the one save the 3/04.
This run and all calibration run can be found in /data/mugastX/mugast |

Valerian | OTHER | Software | N/A | Notes about the electronic |
While doing the electronic scheme, I saw that the Inspection line was inducing a bad signal in the coincidence module between fag and CATS1. See joined image.
Also, I broke a cable between CATS1 Fifo and the delay box, the delay is now 2 ns longer. |

Marlène | GRIT | General | | Alpha source --> status of detectors |
MG3T has been fixed by changing the X kapton.
I have removed aluminium foil on square detectors, the noise is slightly higher.
MG4T is not working properly : noisy on X but no signal on Y !! I see no triggers on the Y side. I tried to increase bias but it did increase noise. I checked in the last calibration of e744 it was working properly. Also I had to do pedestal realignement for this detector because everything was shifted.
MG7T seem to be slightly different than before. Strips X are hidden from the trigger because it became suddenly noisy. |

Marlène | GRIT | General | | MUGAST detectors status --> MG4T |
The problem of MG4T ha sbeen solved by changing the feedthrough.
The pulser on Y was not working and we were seeing no events (no ORD) because there was a problem with the bias of board. The issue is due to the feedthrough.
So now MG4T (HT &BT) are plugged in a free feedthrough (below MG1T) and I see pulser signals on Y.
The bias seems to apply normally on all detectors (in the dark).
The pulser is seen on each boards.
I have put back aluminium foil on square but I could not test it. |
