Abstract

A new type of ultracold neutron (UCN) detector based on Boron-10-coated plastic scintillator is described. The characteristic decay time of the scintillator is less than 10 ns and shorter than earlier detectors based on ZnS:Ag. The light yield within the first 10 ns compares favorably with polycrystalline ZnS:Ag and crystalline LutetiumYttrium Oxyorthosilicate (LYSO). The efficiency of each detector is cross-calibrated against ZnS:Ag using various charge particle sources. Several light coupling and photodetector schemes are evaluated. Plastic scintillator-based detectors are useful options for high-rate, large-area UCN detection applications.
