Square detectors |
|
|
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)
With internal pulser (trigered by CK_TST) the counting rate is OK only if the thresholds are set at 1 MeV. If they are set at 500 keV, the counting rate is 10 times higher than the CK_TST
For MG10C, ORD is OK ! |
