Abstract

This paper presents an evaluation of electron thermal and particle transport coefficients by three different methods: (a) analysis of inward propagation of electron temperature and density perturbations produced when a small pellet is injected into the plasma; (b) measurements of the velocity and damping of electron temperature and density pulses propagating outwards following sawtooth collapse; (c) time dependent transport analysis applied to non-stationary plasmas. The coefficients are determined for ohmically heated deuterium plasmas in JET, limited by the outer carbon belt limiters.
