A detector that measures neutrons between 1 and 10 MeV in a mixed background of charged and neutral radiation was developed for use in cosmic-ray studies. The detector consists of liquid scintillator NE213 surrounded by a thin shield of plastic phosphor NE102 for charged particle rejection. Both scintillators are viewed by a single photomultiplier, in an adaptation of the pulse-shape discrimination technique.
