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
N | 80 cm | 70 cm | 60 cm | 50 cm | 40 cm | 30 cm | 20 cm | 10 cm | 0 cm |
