Unformatted text preview: damping due to resonant particles assuming that | ω-Ω | /kv t ± 1 so that the thermal corrections are weak. The result is the cyclotron damping rate, γ =-√ π ω k 1 + k 2 d 2 | v r | v t e-v 2 r /v 2 t , (3) where v r = ( ω k-Ω) /k is the resonant velocity. Note that the resonance now re-sults when the Doppler shifted frequency equals the cyclotron frequency and that the particle acceleration is associated with a perpendicular rather than parallel electric ﬁeld....
