Description

The purpose of this diagnostic is to detect alpha particles in DT plasmas via spectroscopy using injected lithium pellets as a source of charge exchange particles. It was first proposed by Sasao, et al, in 1987. As of June 1994, we have not seen alpha signals above the bremsstrahlung background via this technique in TFTR DT plasmas. This paper discusses the basis for the measurement, shows existing data, and describes possible actions to improve the measurement attempt on TFTR. (author) 7 refs., 3 figs
