摘要
在激光等离子体相互作用中,受激布里渊散射的模拟耗时较长.为缩短模拟时间,对电子采用Boltzmann描述,开发了一维混合Vlasov程序,利用离子束双流不稳定性理论结果对程序进行了考核.在此基础上对激光聚变中的受激布里渊散射进行了研究,结果表明程序正确,模拟结果可信.
In laser plasmas interactions,the simulation of stimulated Brillouin scattering takes a long time.In order to decrease the simulation time,a hybrid Vlasov code is developed,in which the electrons are treated as Boltzmann fluid.The two-ion beam instability is simulated,and the simulation results are compared with the theoretical results.Stimulated Brillouin scattering is also simulated,the results show the code correctness.
