PMTs expected to be ON/OFF¶
Since this is one of the first time the PMTs are on for a long period, the shifter should fill the ECL form related to the PMT monitoring every hour
The condition of the system for this test is the following:
- East side:
1) Bertan master switch on
2) Bertan current 56 mA, voltage 2000V, values may change during calibrations.
3) All pmts on. PMT 290 display a red alarm and status is set to OverVoltage. This is a known non-working channel and it can be ignored
- West side:
1) Bertan master switch on
2) Bertan current 54 mA at the moment and voltage 2000 V, but values may change during calibrations.
3) All pmts on. PMT 143 display a red alarm and status is set to OverVoltage. This is a known non-working channel and it can be ignored
Channels with empty text boxes and light-gray leds are not connected to a pmt.
