Investigation of the neutron-gamma ray discrimination performance at low neutron energy of a solution-grown stilbene scintillator
Abstract
The results of experiments performed with a Ø25 x
25 mm solution-grown stilbene crystal in mono-energetic neutron
fields in the 80-to-230 keV energy range are presented. The goal of
the measurements, performed at the AMANDE facility, was to
explore the capabilities of this organic scintillator to measure
neutrons at the lowest possible energy with good pulse shape
discrimination (PSD). The time of flight (TOF) technique was used
in order to help with the neutron-gamma discrimination. The data
are collected via a programmable digital acquisition (DAQ) system
CAEN DT7530 using the software CoMPASS with the charge
comparison method (CCM). The data are analysed using postprocessing codes developed in the ROOT environment. The results
show that the stilbene detector has discrimination capabilities for
energies as low as 80 keV.
