Abstract
The electron thermal conductivity χe is calculated from the evolution of the heat pulse immediately after a sawtooth crash as a forced boundary problem. The electron cyclotron emission signal, measured just outside the sawtooth mixing radius, is used as the time dependent boundary condition. This method makes no assumptions about the plasma behaviour inside the mixing radius and permits the accurate determination of the radial dependence of χe.Keywords
