摘要
采用PIC模拟研究了基于等离子体电子枪的小型化束-等离子体系统,探索了等离子体电子枪发射电流随加速电压、阴极等离子体密度、电子束通道半径以及电子束通道长度的变化规律,展示了电子束在高密度等离子体中的聚焦传输行为。
A miniaturized beam-plasma system based on a plasma electron gun is studied with PIC simulation.The effects of acceleration voltage,cathode plasma density,beam channel radius,and beam channel length on the emission beam current are explored.The behavior of focusing transmission of the electron beam in high density plasma is also exhibited.
