摘要
研制了 2 12 维粒子模拟程序PLASIM(PlasmaSimulator) ,介绍经过验证的该粒子模拟程序的算法 ,其特点是自含碰撞 ,即 β 粒子云模型的选取使得该程序无需额外的计算开销就能在程序中自洽地含有碰撞 ,使计算结果更加符合实际情况 .另外电子和离子的运动都是相对论的 ,适于模拟超强激光与等离子体的相互作用 .
A 212 dimensional particle simulation code PLASIM (Plasma and Simulator) is developed with the purpose of studying the interaction of laser and plasma.The algorithm of the code is introduced.A main characteristics of the code is that it can simulate collision effects by adopting β-particle cloud.Another characteristics is that electrons and ions are both relativistic. So the computation results are more believable when incident laser is ultra-intense.
