Description
Plasma heating by directly launched ion Bernstein waves is investigated in the Alcator C tokamak at densities n-bar/sub e/approx. >1 x 10/sup 20/ m/sup -3/. For injected rf powers P/sub rf/approx. <180 kW, bulk ion-temperature increases of ΔT/sub i/approx. <380 eV, as well as improvements in global particle and central impurity confinement times by a factor of 2--3, are observed. In certain regimes, the energy confinement time improves relative to the initial Ohmic value. At higher densities (n-bar/sub e/approx. >2 x 10/sup 20/ m/sup -3/), the heating ceases to be efficient
