Set up like that:
The voltages and thresholds are:
| PMT voltage, V | threshold, mV | discr. width, ns | |
|---|---|---|---|
| PS1 | -1500 | -80 | 100 |
| PS1 | -1500 | -80 | 100 |
| n's | -1500 | -200 | 10 |
Let's do the timing test. The distances are between PS1+PS2 and n's PMT. The time is time difference between PS1(PS2) and n's detector signals
| dist. between PS1(PS2) and n's PMT | time difference |
|---|---|
| 80 cm | |
| 70 cm | |
| 60 cm | |
| 50 cm | |
| 40 cm | |
| 30 cm | |
| 20 cm | |
| 10 cm |
