Stopping Power for Ions Moving in Magnetized Plasma

Abstract

Stopping power of test ions in magnetized plasmas is investigated by means of linearized Vlasov Poisson theory. The influences of the magnetized field, the angle between the test particle velocity and magnetized field, and certain plasma densities and temperatures on the stopping power are studied. Simulation results show that the stopping power emerges a peak around the plasma thermal velocity due to the electron excitation. When the magnetized field is strong, the stopping power is strengthened; while when the magnetized field is weak, the stopping power is weakened.
