Outline of Final Research Achievements

This project aims to investigate the fast ion physics in magnetically confined plasma. For this purpose, we developed the microwave collective Thomson scattering (CTS) by using a high power gyrotron. CTS can measure both thermalized bulk ion components and non-thermalized fast ion components.
Two detection systems were developed. One is a filter bank system with slow digitizer (100kHz sample for 80sec) to measure temporal evolution of CTS spectrum, the other is a fast digitizer system (10GHz sample for 80msec) to measure fine structure of CTS spectrum. Scattering geometry was optimized for the precise measurements in order to reduce stray radiation. Measured CTS spectrum was compared with theoretical model calculated by numerical code, then, qualitative agreements were obtained. From the measurements of bulk ion components by using a fast digitizer system, ion density ratio was measured from the modulated spectrum due to ion Bernstein waves.
