Hybrid simulation of stimulated Brillouin scattering in laser fusions

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．

Abstract: 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.
