内容記述 | The study of heavy-ion acceleration by magnetosonic shock waves in multi-ion-species plasmas [M. Toida and Y. Ohsawa, Solar Physics 171, 161 (1997)] is extended to the case in which the ion masses are of the same order of magnitude; specifically, the effect of mass and density ratios is examined for H-T and D-T plasmas with three-dimensional, electromagnetic, particle simulations. The frequency difference Δ_ω, where Δ_ω=(ω_+0−ω_−r)/ω_+0 with ω_+0 the cut-off frequency of the high-frequency magnetosonic mode and ω_−r the resonance frequency of the low-frequency mode, is a key parameter in the generation of shock waves from a disturbance. In H-T plasmas with n_H<<n_T and with n_H>>n_T and in D-T plasmas with any density ratio, Δ_ω is small, and the high-frequency-mode shock wave is mainly generated and plays a central role in ion energization processes. In H-T plasmas with n_H=n_T, for which Δω is much greater, both the high- and low-frequency-mode shock waves are generated and contribute to the acceleration. | |||||
