Abstract

This report contains papers originally presented at a workshop on electron cyclotron emission and electron cyclotron resonance heating. The design and performance characteristics of the JET heterodyne radiometer are reviewed and a current project to develop neural network techniques for the conversion of JET ECE spectra to electron temperature profiles is reported. The effect of a fast electron population on the ability to make reliable temperature measurements using ECE is described, and the potential of ECE measurements on Next Step tokamaks is discussed. The design of a diagnostic system to measure electron cyclotron absorption at the second harmonic E-mode resonance in the JET pumped divertor plasma is also included.
