 What about the PS's detectors. I can concluded that detectors works good, detects the cosmic, and increase the counts as the external source approaches the detectors.
-What about the n's detector. The counts rate is basically the same with and without the source CF243. So what we are really detect? Cosmic? Then why the rate does not depend from source. Some internal noise? But why the count rate are so big?

 I am going to increase the power supply for HAMAMATSU, adjust threshold  and see what happens.
