A set of neutron time-of-flight detectors, based on the design of the VANDLE detector, is currently being built at the University of Warsaw. The objective is to construct mobile, small form-factor detectors, suitable for 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 plastic bars read from one end using silicon photomultipliers equipped with the custom-designed electronic front-ends and a fully digital electronic acquisition system. Preliminary results of time resolution and detector response to radiation measured with gamma-ray sources are presented. [ABSTRACT FROM AUTHOR]
