Study Of Thermal Flux And Self-Generated Magnetic Field In Instability In Anistropic Plasmas

With the rapid development of laser technology,especially the invention of the pulse amplification(Chirped pulse week Amplification,CPA)technology,which can obtain human super light field hitherto unknown in the laboratory,which greatly expanded the research field of the interaction between light field and matter,besides,enriching the research of laser particle acceleration in the connotation of the laser electronic development,such as laser electron acceleration,ion acceleration,laser nuclear physics,nonlinear and even vacuum physics.As a new kind of optical medium,plasma has no thermal damage threshold.It has been a hot research direction at home and abroad to control strong light pulse and amplification laser field.Ultrashort pulse laser power can reach 1022 W/cm2,provides the power density,hitherto unknown to human electric field strength,magnetic field intensity,high temperature,high pressure and other experimental conditions very difficult,for the innovative research and breakthrough in many disciplines provide the important experimental platform.The interaction between plasma and plasma is an important problem of inertial confinement fusion(ICF).The main content of this paper is divided into four parts:Firstly,we briefly introduced the historical background of the development of ultra-intense laser pulse and plasma,the laser inertial confinement fusion,and the research significance of interaction between super laser pulse and plasma.Secondly,we mainly introduce the theoretical basis of the interaction between the super laser pulse and the plasma,including the optical field ionization,plasma-related physical parameters,and so on.Thirdly,according to the basic content of the plasma dynamics theory,using the Vlasov equation and Maxwell's equation to deduce the relationship between the heat flow variation and the self-generated magnetic field in the non-relativistic method.Finally,we mainly studied the mechanism of self-generated magnetic field in theplasma caused by the velocity anisotropy distribution.
