Polarization effect and energy loss in interactions of charged particles with magnetized plasmas

The energy loss of charged particles moving in magnetized two-component plasmas has been studied based on the linearized Vlasov-Poisson equations, in which special attention is paid to the effects of the magnetic filed and dynamic polarization on the energy loss. The numerical results show that there are two peaks in the energy loss. One is located in the low-velocity region and corresponds to the ion’s polarizations, and the other is located in the high-velocity region and corresponds to the electron’s polarizations. In the case of the strong magnetic filed, the energy loss of the low-velocity particles is mainly caused by the ion’s polarizations; while in the case of weak magnetic filed, the energy loss of the high-velocity particles is mainly caused by the electron’s polarization．
