Abstract

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