摘要: 设计了一个二维混合模拟程序,并用其计算了等离子体物理中的束流不稳定性.结果表明,此程序在计算过程中使能量基本保持守恒,计算结果同理论分析及一维混合模拟结果相一致.

关键词: 混合模拟, 束流不稳定性

Abstract: Hybrid codes treat ions as particles and electrons as fluid to study physical problems in plasma. A 2D hybrid code is designed, and in order to test it, the beam instabilities in plasma using this code is studied. The results coincide with the theoretical analysis and 1D hybrid simulations.

Key words: hybrid simulations, beam instabilities
