Set up like that:

Detector1.png


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
