中文摘要: 利用高功率激光与高Z材料黑腔相互作用产生高温、对称、干净的辐射源是高能量密度物理领域重要的研究内容之一。在高功率、长脉冲激光条件下,黑腔内部的等离子体填充和激光等离子体非线性过程是目前影响黑腔辐射品质的两个主要因素。项目组提出利用兆高斯量级轴向磁场抑制腔内的等离子体填充和激光等离子体非线性过程。为了在黑腔内部产生兆高斯量级的轴向磁场,本项目在电容-线圈靶的基础上提出了电容-黑腔靶,拟利用高功率激光打靶在黑腔内部产生兆高斯量级的轴向磁场,然后开展激光与磁化黑腔相互作用的实验研究。本项目对黑腔能量学、激光与磁化等离子体相互作用等方面的研究都具有重要的意义。

英文摘要: Generating high temperature symmetrical clean radiation source by the interaction of high power laser with high-Z hohlraum is one of the important research contents of high energy density physics. Under conditions of high power long pulse laser, plasma filling and laser-plasma nonlinear process are two major factors influencing hohlraum radiation quality. This project group proposed using axial megagauss magnetic field to suppress plasma filling and laser-plasma nonlinear process. The capacitor-hohlraum target was put forward based on capacitor-coil target, so megagauss axial magnetic field can be generated in hohlraum by the interaction of high power laser with capacitor-hohlraum target, and then the interaction of laser with the magnetized hohlraum can be investigated. This project is of great significance in hohlraum energetics and laser interaction with magnetized plasma.
