A New Neutron Time-of-Flight Array for β-Decay Studies

Abstract

A new time-of-flight array for β-delayed neutron spectroscopy (E n < 5 MeV) is being developed with the aim of improved performance compared to existing arrays. We report on the status of this development, in particular the study of the n-γ discrimination quality with digital electronics, a comparison of several organic scintillators, including new discriminating plastics, as well as the characterisation of detectors with monoenergetic neutrons to measure intrinsic efficiencies and cross-talk probabilities.
