新的实验能力[Froula et al., Phys.]Rev. Lett. 98, 085001(2007)]已经开发用于在Omega激光设备（LLE/Rochester）的点火相关条件下研究激光等离子体相互作用（LPI）。在加热光束能量高达17kJ的情况下，沿着充满气体的热腔的轴线发射相互作用光束，产生了电子温度高于3keV的毫米级低密度均匀等离子体。广泛的汤姆逊散射测量允许对HYDRA进行的流体动力学模拟进行基准测试[Meezan等，物理学家]。等离子体学报，2014 (5)；通过这些努力，这些模拟结果可以作为LPI模拟代码PF3D的输入参数[Berger等人，物理学家]。等离子体5,4337(1998)]。本文表明，通过精确的水动力剖面和全三维模拟，包括对各种平滑选项产生的激光强度图的逼真建模，整个光束三维线性运动…
New experimental capabilities [Froula et al., Phys. Rev. Lett. 98, 085001 (2007)] have been developed to study laser-plasma interaction (LPI) in ignition-relevant condition at the Omega laser facility (LLE/Rochester). By shooting an interaction beam along the axis of a gas-filled hohlraum heated by up to 17kJ of heater beam energy, a millimeter-scale underdense uniform plasma at electron temperatures above 3keV was created. Extensive Thomson scattering measurements allowed to benchmark hydrodynamic simulations performed with HYDRA [Meezan et al., Phys. Plasmas 14, 056304 (2007)]. As a result of this effort, these simulations can be used with much confidence as input parameters for the LPI simulation code PF3D [Berger et al., Phys. Plasmas 5, 4337 (1998)]. In this paper, it is shown that by using accurate hydrodynamic profiles and full three-dimensional simulations including a realistic modeling of the laser intensity pattern generated by various smoothing options, whole beam three-dimensional linear kinet...
