PMT and particle detector settings |
|
|
Final voltages and thresholds for the PMTs and particle detectors before the first scan:
|
Detector | voltage (kV) | threshold (mV) | mesytec
| |
particle detector | 1.35 | 100 | -
| |
PMT north | 2.7 | 10 | 16
| |
PMT mid | 2.65 | 10 | 16
| |
PMT south | 2.7 | 10 | 16
|
All other mesytec thresholds remain unchanged and can be found in entry 7.
Important note: Ch0 of the PMT power supply broke, so we moved PMT north to CH3.
Current setup:
CH1: PMT mid
CH2: PMT south
CH3: PMT north |
