In this new Application Note (AN3250) Pulse Shape Discrimination between neutrons and gamma rays in liquid scintillators is studied by using DPP-PSD firmware running on CAEN digitizers. The dependence of the Figure of Merit on the digitizer sampling rate and resolution is experimentally determined.
Based on "Pulse shape discrimination with fast digitizers", L. Stevanato et al, NIMA 748 (2014) 33-38, DOI: 10.1016/j.nima.2014.02.032
For the measurements reported in this application note, a liquid scintillator coupled to a 12 dynode photo-multiplier (PMT) has been used. The anode signal was directly processed by a set of CAEN digitizers running DPP-PSD firmware:
