Effects of Particle Bounce Motions on ICRF Heating Mechanism in Simple Mirror Discharge

Effects of ion and electron bounce motions on ICRF (Ion Cyclotron Range of Frequency) heating mechanism in simple mirror discharge are investigated theoretically. As a preliminary study, we consider a one-dimensional model in which propagating R (Right-handed circularly polarized) and L (Left-handed circularly polarized) waves interact with mirror-trapped ions and electrons. The results show that ion bounce resonance effect with L-wave can occur under the condition that ω_ci < ω.
