Colorado School of Mines fusion gamma ray diagnostic project

The purpose of our fusion gamma ray project continues to be the development of fusion gamma ray spectrometry as a diagnostic of high temperature fusion plasmas. The three broad areas in support of this purpose are: Measurement of gamma ray producing reactions at low energies; development of gamma ray spectrometers capable of measuring the gamma ray yields from current and proposed fusion plasma devices; and determination of appropriate plasma parameters from measured fusion gamma ray yields at present fusion plasma devices. This report summarizes the progress made in these three areas. In the next section we summarize our recently completed measurement of the radiative capture of protons by the nuclei 6Li, 7Li, 9Be and 11B. We also present preliminary results of our investigation of the radiative capture of deuterons by 6Li and 10B as well as additional data taken on the reaction D(d,γ)4He at very low energies
