The ECE diagnostic system on TEXTOR
Description
A heterodyne millimeter wave radiometer was built to record simultaneously the first ordinary and second extraordinary wave of ECE emitted from the same point in the plasma. The optical depth of the TEXTOR plasma was calculated for typical TEXTOR parameters. The accessibility of ECE-radiation was considered. First experimental results from TEXTOR are presented. The electron temperature on axis of the TEXTOR plasma is routinely monitored from ECE intensity measurements. An instantaneous half electron temperature profile and its development in time are shown. Internal plasma disruptions are visualized by a sawtooth modulation of the ECE intensity. Also MHD-activity in the plasma is reflected in the ECE. (orig.)
