Use of gamma-ray-generating nuclear reactions for temperature diagnostics of DT fusion plasma.
A diagnostic application of gamma rays emitted in 6Li+D and 6Li+T nuclear reactions induced by admixing a small amount of 6Li in DT fusion plasma is investigated. It is shown that the reaction-produced monochromatic gamma quanta with energies E(gamma)=0.429, 0.478, and 0.981 MeV can be used for ion temperature measurements in DT plasma. The proposed measurements are expected to be essentially independent of the plasma density and its local fluctuations. The required reaction cross sections and the Maxwellian rate parameters of the 6Li+T gamma-ray production are calculated within a realistic nuclear model.
