Alpha source run for trapezoid detectors + anulaire detector with pedestals aligned (with HV Frown ) and zero suppression. Cooling at 15°C.
Thresholds at 500 keV.

4--> MG11 (60V)

TRIGGERS are:

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.
