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. |

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)

Offline analysis to reconstruct the charges in X and Y for CATS.
The charges are lower in RUN77 because bias was reduced to 580V.
Wires seem to be all OK. |

Fixed, e786s, Fri May 31 09:53:14 2019, 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.

|
Fixed, e786s, Mon Jun 3 18:00:10 2019, 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.

|
We observe a change in the Brho of VAMOS : the charged states are divided in 2 !!!
Édit: it is now understood as ice water cracking on the upstream of the target. |
