A measurement of hydrogen transport in deuterium discharges using the dynamic response of the effective mass

Abstract

Particle tagging in a tokamak provides an attractive method for studying transport mechanisms. The injection of test particles at the plasma edge and the subsequent measurement of the evolution of their concentration at the centre can be used to quantify the underlying transport mechanisms. This has been carried out on the TCA tokamak by injecting hydrogen into a deuterium discharge, and simultaneously measuring the temporal evolution of the effective mass and the edge ionisation rate. (author) 3 figs., 9 refs.
