抜粋

Nonlocal eigenmode of ion cyclotron range of frequency instability in the presence of parallel high energy beam component is obtained in a toroidal plasma in an inhomogeneous magnetic field. The mode is the combination of the fast wave and Bernstein wave and is excited via kinetic interactions with beam particles. When the driving source of high energy particles overcomes the total dampings due to the bulk plasma and the resistive loss on the wall, the instability can occur. Nonclassical energy/momentum transfer rates due to this mode between different plasma species are obtained. Nonlocal energy/momentum transport is simultaneously induced. The rate of nonclassical energy transfer reaches the classical level at the low level of wave amplitude.
