The neutralization of an ion beam pulse directly by electron injection excites the two-stream instability of neutralizing electrons and gives rise to an electrostatic solitary wave (ESW) in the long time limit. The ESW propagates stably and reflects

The possibility of exciting electrostatic solitary waves (ESWs) during the neutralization of ion beam pulses by plasmas is investigated using a two-dimensional (2D) electrostatic particle-in-cell (PIC) code. The simulation results show that if an axi

Ion beam charge neutralization by electron injection is a complex kinetic process. Recent experiments show that the resulting self-potential of the ion beam after neutralization by plasma is much lower than the temperature of plasma electrons [Stepan
