HV & functionality test
- Test a batch (up to 96) of tubes filled with standard gas mixture for a long time
- Slowly rise voltage while controlling current
- Drop voltage and rise it again if necessary for tube training
- Keep low humidity in test area
Based on CAEN 546 HV power supply module:
- 96 chanels , voltage is set by groups of 12
- Current in each channel is controlled with 1 nA accuracy
L3 amplifier, 32-channel discriminators and 16-channel CAMAC scalers are used to control count rate
Test procedure is automatic
~1 hour for tube connection
+ 1.5-12 hours for the test itself
Leak current limit : 2 nA/m
