A high resolution neutron spectrometer, based on the magnetic proton recoil (MPR) technique, is under construction for use on JET. It is designed for the planned high power DT experiments to make use of the very high neutron fluxes (up to a few times 10[sup 10] n/cm s) obtainable at vantage points close to the plasma. This will be used to operate at highest possible neutron count rates ([ital C][sub [ital n]]) to facilitate plasma measurements of maximum (statistical) accuracy without need of excessive integration times. The JET experimental conditions will permit operation in the MHz range ([ital C][sub [ital n]][le]0.5 MHz compared to [ital C][sub [ital n]][le]10 MHz on ITER). Prototype tests are planned to be performed with the MPR spectrometer besides diagnostic studies of the JET plasmas. We will describe the principles of the spectrometer and the research plans.
