Abstract
The influence of a sampling rate of ADC on the efficiency of the pulse shape discrimination procedure (PSDP) developed for gamma-neutron discrimination was studied. Pu-Be neutron source and two types of digitizers (CAEN DT5730 and CAEN DT5743) were used. Both digitizers together with application software allow to store sequences of waveforms from a scintillation detector. The functional features of the CAEN DT5730 and CAEN DT5743 are described, and experimental characteristics of their operation are compared. Experimental values of an efficiency of neutron/gamma signal discrimination using two ADCs with different sampling frequencies are presented.
Highlights
There are several applications which require a parallel detection of fast neutrons and gamma radiation: 1) a monitoring of neutron and gamma background in low-background underground experiments [1], 2) a measurement of a fast neutron yield from neutron generators [2, 3], 3) a monitoring of a spent nuclear fuel, 4) an environmental monitoring on nuclear power plants
Scintillation detectors with organic crystals, plastic and liquid scintillators are used for such a technique of a radiation detection
We studied and present in this paper how differs an efficiency of the same pulse shape discrimination procedure (PSDP) from the type of ADC with a different sampling rate and an accuracy
