Abstract

In this work, we compare the pulse-shape discrimination (PSD) properties of newly developed liquid scintillators LSB-200, EJ-299-33A, BC-501A, stilbene, p-terphenyl and Hidex Aqualight in neutron field generated by the LVR-15 reactor with silicon filter utilization. Pulses from the scintillators are processed by the Neutron-Gamma spectrometer. This spectrometric system with fast digitizer card contains two analog-digital (A/D) converters with a resolution of 12 bits and sampling frequency of 500 MHz. We used active divider to improve linearity of the photomultiplier (PMT). Measured data from scintillators have been processed using the integration method and compared. The results are presented.
