Shaing, K C; Conn, R W

The dispersion relation for the drift-cyclotron loss-cone (DCLC) mode in the presence of the lower hybrid wave is calculated using both electrostatic and finite ..beta.. models. It is found that there exists a critical beta, ..beta../sub c/, such that when ..beta.. > ..beta../sub c/, an rf wave of frequency ..omega../sub 0/ greater than the lower hybrid frequency ..omega../sub LH/ can stabilize the drift cyclotron loss cone mode in a mirror plasma. For ..beta.. < ..beta../sub c/, the rf wave can stabilize this mode only when the wave frequency ..omega../sub LH/ < ..omega../sub 0/ < ..omega..*. In either case, if ..omega../sub 0/ is much greater than ..omega../sub LH/, the wave has little effect on the DCLC mode.
