Colorado School of Mines fusion gamma ray project: Technical progress report

This report summarizes the technical accomplishments of the first year of a contract between the Colorado School of Mines and the US Department of Energy entitled ''Fusion gamma ray diagnostics of alpha particle production and confinement in the Compact Ignition Torus'' No. DE-FG02-88ER53276. The stated goals of the contract were to: develop a high count rate gamma ray spectrometry system; install the system on TFTR and carry out measurements of alpha particle production during ICRH d-3He plasmas as benchmarks for similar proposed measurements on CIT; and, assess the feasibility of fusion gamma ray diagnostics of alpha particle confinement. We have completed the first objective, are in the process of implementing the second objective and are making some very preliminary progress in the third. In addition to the above stated goals, we have, in connection with a separate contract with the DOE Office of High Energy and Nuclear Physics, completed gamma ray branching ratio measurements of the p-6Li and p-11B reactions at proton bombarding energies down to 40 keV. These gamma ray branching ratios will provide the basis for gamma ray diagnostics of future ''advanced fuel'' fusion reactor systems and hence are reported in this progress report
