Description

An ion Bernstein Wave (IBW) Heating experiment has been carried out on the JIPP T-II U Tokamak in combination with NBI and fast wave heating, where an IBW branch between the 4th and 3rd harmonics of the hydrogen ion cyclotron frequency was used, the frequency being 130MHz. Parallel refractive index can be chosen to be N// = 4 or 8. RF power up to 400kW has been injected so far, which is about 4 times the previous experimental level at 40MHz. Core plasma heating has been observed as well as an electron density increase near the plasma axis. The heating efficiency is improved with simultaneous fast wave heating. (author) 7 refs., 4 figs
