Abstract

THE WORKSHOP DISCUSSES IMPROVEMENTS TO THE ECE DIAGNOSTIC SYSTEM. ELECTRON TEMPERATURES MEASURED BY ECE ARE COMPARED TO THOSE OBTAINED BY THOMSON SCATTERING. THE MEASUREMENTS ARE SHOWN TO AGREE WITHIN EXPERIMENTAL UNCERTAINTY. TWO-DIMENSIONAL PROFILES OF ELECTRON TEMPERATURE ARE CALCULATED FROM ONE-DIMENSIONAL PROFILES MEASURED WITH FOUR VIEWING CHANNELS. ISOTHERMAL CONTOURS USUALLY FIT THE FLUX SURFACES WITHIN THE UNCERTAINTY OF THE ECE INTERCHANNEL CALIBRATION. THERE WAS GOOD AGREEMENT BETWEEN MEASURED, SPECTRA AND THOSE CALCULATED BY A COMPREHENSIVE EMISSION CODE. PAPERS DEALT WITH A TECHNIQUE FOR IMPROVING THE RELATIVE ACCURACY OF JET ECE TEMPERATURE PROFILES, A FEASIBILITY STUDY OF MICROWAVE METHODS FOR THE CALIBRATION OF ECE SPECTROMETERS, AND THE IMPROVEMENT OF HIGH SPATIAL RESOLUTION TEMPERATURE MEASUREMENTS IN JET USING A MULTI CHANNEL HETERODYNE RADIOMETER.
