质子照相是观测等离子体中自生磁场的常用实验诊断技术,对质子照相实验结果的有效解读依赖于反演方法的可靠性和可用性.传统质子照相反演方法往往只能提供自生磁场的一维或二维结构.本研究发现,在对具有柱对称结构的磁场进行侧向质子照相时,偏转速度与磁场之间满足Abel变换关系,这使得从质子照相结果中反演重建出磁场的三维结构成为可能.通过数值模拟验证了该方法的可行性,并基于该反演方法,重新分析了Li等(2016 ***.713081)有关等离子体喷流自生磁场的质子照相实验结果,给出的最大磁场强度约为传统反演结果的1.9倍.本研究有助于对激光聚变和实验室天体物理相关的自生电磁场形成及其时空演化行为的认识更加清晰.

应用一维Vlasov和Maxwell耦合程序详细研究了激光等离子体相互作用中的基本问题——受激拉曼散射(SRS).通过研究发现,SRS的产生与电子速度分布函数在相空间中的结构密切相关,当电子速度分布函数形成相空间涡旋时,背向SRS光大幅增加,而当电子等离子体波相速度附近的电子速度分布函数曲线变平坦后,背向SRS光基本停止发生.在模拟中观测到了SRS的爆发、电子速度分布函数形成相空间涡旋、电子俘获等清晰的物理图像.
