Abstract
The need for simultaneous neutron and gamma detection continues to motivate the development of dual mode radiation detectors. One promising candidate is the elpasolite inorganic scintillator Cs 2 LiYCl 6 :Ce (CLYC). Previous studies, with other dual neutron–gamma detectors (EJ-299/EJ-309), have shown that the choice of digital data acquisition (DAQ) system can significantly affect pulse shape discrimination (PSD) performance. In this work, results are presented from a 2″ CLYC crystal, with Photomultiplier Tube (PMT) pulses captured by CAEN V1751 and V1730 digitizers. Through offline analysis, PSD performance was explored as a function of digitization parameters (sampling frequency, ADC resolution). Particular attention was given to assessing where diminishing returns may lie, so that reductions to the size and power requirements can be made for use with compact CLYC detector systems in the future.
