A full-integrated pulse-shape discriminator for liquid scintillator counters

A low-cost high-performance pulse-shape discriminator for neutron–gamma discrimination using liquid scintillation counters equipped with two photomultipliers is developed. Two independent methods of pulse-shape discrimination are exploited to achieve an optimum neutron–gamma identification. The circ...

Description
Summary:A low-cost high-performance pulse-shape discriminator for neutron–gamma discrimination using liquid scintillation counters equipped with two photomultipliers is developed. Two independent methods of pulse-shape discrimination are exploited to achieve an optimum neutron–gamma identification. The circuit is especially designed to study the low-intensity neutron background field in the Gran Sasso underground laboratory. A detailed layout and the main performances of the electronic circuit are described.
