The application of the bubble detector to the measurement of intense neutron fluences and energy spectra

A novel type of bubble detector is developed which can measure neutron fluences on the order of 10/sup 11/ n/cm/sup 2/ (or a few grays). These detectors use superheated droplets which are much smaller than those in conventional bubble detectors. Preliminary studies involving several types of these microdroplet detectors having different neutron energy thresholds have been performed. The goal is to develop a set of such detectors which can be used as a simple neutron spectrometer needed in connection with TREE applications.<
