The spatial and temporal evolution of the pulsed plasma sheath is simulated using the particle-in-cell method. The effects of pulse parameters such as the rise time, duration, and maximum voltage on the sheath characteristics are discussed. In addition, it is considered how the pulse parameters affect ion current density, and ion kinetic energy at the cathode surface. It is found that even in the absence of collisions, the pulse rise time can broaden the energy distribution of ions at the cathode surface and the ion energy distribution is determined by the ratio of the pulse duration to the rise time.

脉冲等离子体鞘的细胞模拟中的粒子：对脉冲参数的依赖性

脉冲等离子体鞘的空间和时间演化使用细胞内粒子方法进行模拟。讨论了脉冲参数如上升时间、持续时间和最大电压对护套特性的影响。此外，还考虑了脉冲参数如何影响离子电流密度和阴极表面的离子动能。研究发现，即使在没有碰撞的情况下，脉冲上升时间也可以拓宽阴极表面离子的能量分布，离子能量分布由脉冲持续时间与上升时间的比值决定。
