| Research Abstract |
The collective Thomson scattering(CTS) system by using a high power gyrotron was developed and installed in Large helical Device in order to measure fast ion distribution of magnetically confined plasmas. The CTS measures electron density fluctuation induced by the thermal ion motions. From the spectrum shape, temperature and density of ions can be estimated. The measurement system was developed, and then CTS signal was obtained from plasmas of the Large Helical Device. However, further developments are necessary to improve the measurement accuracy for the physics study.
