Subject: 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.
