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. |
