| 摘 要： | 利用柱坐标系下的二维PIC程序对金属靶背向超热电子束的运动特性进行了模拟，研究了超热电子的回流机制。通过对不同参数情况的比较，发现在单能情况下电子的出射率有振荡现象，而对于能量为Maxwell分布的电子，振荡趋于光滑。

| Abstract: | The kinetic features of super hot electrons emitting out of the rear side of metal target is simulated and the reflux is studied by a two-dimension PIC code in cylindrical coordinates.The results show that the emission ratio oscillates when the super hot electron beam is mono-energetic,and the oscillation is smoothed when the electron energy distribution is Maxwellian. |

| Keywords: | Separation potential Super hot electron Emission ratio Oscillation |
