Because is something wrong I decided to measure the counts rate as function of threshold energy. Maybe my threshold was incorrect.
Below are my results for n's detector with HAMAMATSU PMT (-1500 V):
So it looks like my previous threshold value (-500 V) was not good. Let's set it up the -200 V. And let's see does the n's detector sensitive to the source
