By Dr. Dale suggestions to make threshold adjusting of n's detectors by looking on difference of count rate with and without source as function of threshold I did the following test.
Set up like that:
The voltages, thresholds and widths are:
| PMT voltage, V | threshold, mV | discr. width, ns | |
|---|---|---|---|
| PS1 | -1000 | -100 | 50 |
| PS1 | -1000 | -100 | 50 |
| n's | -1500 | varying | 10 |
