Set up like that:

Detector1.png

the distance between PS and n's PMT is abot 80 cm


The voltages and thresholds are as below. Note: I increased my thresholds for PS1 and PS2 from 80 mV up to 100 mV according to mu previous calibration threshold line.

PMT voltage, V threshold, mV
PS1 -1500 -80
PS1 -1500 -80
n's -1500 -200


Let's do first the coincidence test PS1+PS2

counts time counts/sec
PS1 2823[math]\pm[/math] 20 min [math]\pm[/math]
PS2 3091[math]\pm[/math] 20 min [math]\pm[/math]
PS1+PS2 93[math]\pm[/math] 20 min [math]\pm[/math]
