Set up like that:
The powers are:
PS1 and PS2: -1000 V (the old 2-channel TENNELEC TC952) n's: -1500 V (the new 2-channel C.A.E.N N471)
The thresholds are:
PS1 and PS2: -80 mV n's: -200 mV
Let's do first the coincidence test PS1+PS2
| counts/min (1 min test) | counts/min (1 min test) | counts/min (5 min test) | counts/min (5 min test) | avg counts/min | |
|---|---|---|---|---|---|
| PS1 | 187 | 160 | 166 | 160.8 | 168.4 |
| PS2 | 187 | 170 | 180.4 | 184.4 | 180.4 |
| n's | 205 | 204 | 201.2 | 202.4 | 203.2 |
