Study on the electron-cyclotron-emission diagnostics on JT-60U
- 1. Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)
Description
Diagnostic system for electron cyclotron emission(ECE) in JT-60 have been surveyed. At JT-60 there are three different ECE-systems: a Fourier transformed spectroscopy system(FTS), a grating polycromater system(GPS), and a heterodyne radiometer system(HRS). Each of the systems has been examined to understand the instrumental feature with much attention to the sensitivity and the resolution. FTS has been studied with particular interest because of its continuous and wide spectral coverage and reliable characteristics for calibration. Some topics in instrumentation for FTS are discussed to get an insight on the system specifications optimal for tokamak experiments. Finally, experimental results of FTS with black body radiation at liquid-nitrogen temperature are described in connection with the calibration of the light guiding system for ECE from JT-60 plasma. 14 refs.
