Warsaw Time-of-flight Neutron Detector

摘要

A set of neutron time-of-flight detectors, based on the design of theVANDLE detector, is currently being built at the University of Warsaw.The objective is to construct mobile, small form-factor detectors, suitablefor use as auxiliary extension in the existing beta-decay spectroscopy decay stations in cases where beta-delayed neutron emission is an important decay path. The detectors are based on 15 × 15 × 200 mm3 plasticbars read from one end using silicon photomultipliers equipped with thecustom-designed electronic front-ends and a fully digital electronic acquisition system. Preliminary results of time resolution and detector responseto radiation measured with gamma-ray sources are presented.
