NON-STOCHASTIC HEATING OF MAGNETIZED PLASMA BY ELECTROSTATIC WAVE

When an electrostatic wave is suddenly applied, initially trapped particles suffer a rapid, large acceleration as well as the stochastic heating, while initially untrapped particles suffer only the stochastic heating. When the bounce frequency ωB is larger than (ωcω)1/2, the initially trapped particles mainly absorb the wave energy and form a high energy tail. The results are applied to the problem of energetic ion creation in laser fusion plasma and of a high energy tail formation in a plasma heated by the lower hybrid wave. © 1979, THE PHYSICAL SOCIETY OF JAPAN.
