NEUTRON DOSIMETRY, SPECTROMETRY, AND NEUTRON ACTIVATION ANALYSIS

Abstract

A thorough investigation of the leakage spectrum from the MITR (MIT Reactor) has been carried out using the MITR fast chopper. These measurements were made for three different fuel loadings, in the energy range from 0.001 ev to 10 Kev. They were compared with several theoretical models and are in fairly close agreement with the heavy gas model. A semiconductor neutron spectrometer is described that will be used for high energy spectrum measurements. A triple coincidence pair spectrometer designed for high efficiency is described. Calibration results using Na24 are reported. Operation of a six meter bent quartz crystal spectrograph for capture gamma ray measurements is described.
