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
