Multiple self-emission x-ray images are used to measure tomographically target modes 1, 2, and 3 up to the end of the target acceleration in direct-drive implosions on OMEGA. Results show that the modes consist of two components: the first varies linearly with the laser beam-energy balance and the second is static and results from physical effects including beam mistiming, mispointing, and uncertainty in beam energies. This is used to reduce the target low modes of low-adiabat implosions from 2.2% to 0.8% by adjusting the beam-energy balance to compensate these static modes.

在OMEGA上直接驱动配置中嵌入的目标的3D低模的超比例控制

在OMEGA上的直接驱动内爆中，使用多个自发射X射线图像测量X射线断层扫描的目标模式1、2和3，直至目标加速度的终点。结果表明，该模式由两个部分组成：第一个随激光束能量平衡线性变化，第二个是静态的，是由物理影响（包括光束模糊，指向错误和光束能量的不确定性）导致的。通过调整光束能量平衡以补偿这些静态模式，可以将低绝热内爆的目标低模式从2.2％降低到0.8％。
