Set up like that:
The voltages and thresholds are:
| PMT voltage, V | threshold, mV | |
|---|---|---|
| PS1 | ||
| PS2 | ||
| n's det |
note: I increased my thresholds for PS1 and PS2 from 80 mV up to 100 mV according to mu previous calibration threshold line.
- ▫ PS1 and PS2: -1000 V
- ▫ n's: -1500 V
The thresholds are:
- ▫ PS1 and PS2: -80 mV
- ▫ n's: -200 mV
Let's do first the coincidence test PS1+PS2
| counts | time | counts/sec | |
|---|---|---|---|
| PS1 | |||
| PS2 | |||
| PS1+PS2 |
