Ion Bernstein wave heating (IBWH) utilizes the ion Bernstein wave (IBW), a hot plasma wave, to carry the radio frequency (rf) power to heat the tokamak reactor core. Earlier wave accessibility studies have shown that this finite-Larmor-radius (FLR) mode should penetrate into a hot dense reactor plasma core without significant attenuation. Moreover, the IBW's low perpendicular phase velocity ([omega]/[ital k][sub [perpendicular]][approx][ital V][sub [ital Ti]][much lt][ital V][sub [alpha]]) greatly reduces the otherwise serious wave absorption by the 3.5 MeV fusion [alpha] particles. In addition, the property of IBW's that [ital k][sub [perpendicular]][rho][sub [ital i]][approx]1 makes localized bulk ion heating possible at the ion cyclotron harmonic layers. Such bulk ion heating can prove useful in optimizing fusion reactivity.
