内容記述 | "An implicit-particle simulation of the collisionless parallel shock created at the interface between an injected beam and a stationary plasma is performed in one dimensional geometry with kinetic electrons inclusive. Electromagnetic waves with the right-hand circular polarization propagating upstream (R^- waves) are generated at the interface of the two plasmas. The R^- waves decelerate the injected beam to form a shock. The shock transition region is not monotonic but consists of two distinct regions, a pedestal and a shock ramp. The length of the transition region which contains the plasma interface is a few thousand electron skin depths. The parallel shock is non-stationary and repeats collapse and re-formation periodically in time. The right-hand circularly polarized electromagnetic waves propagating downstream (R^+waves) are repeatedly excited at the shock ramp. Nonlinear wave-particle interaction between the beam and the R^+ waves causes wave condensation and density modulation. The R^+ waves are considered to sweep away the downstream plasma to suppress its thermal diffusion across the shock." | |||||
