在4omega Thomson散射诊断的支持下，我们首次对惯性约束聚变黑洞中的电离平衡进行了X射线能谱测量。实验数据与非LTE辐射流体动力学计算的平均Au电荷态和电子温度相一致。这些发现与黑洞辐射场的成功集成模拟是一致的。与详细的合成光谱计算的比较表明，实验电离分布略有移动，表明非稳态动力学。
We present the first x-ray spectroscopic measurements of the ionization balance in inertial confinement fusion hohlraums supported by 4omega Thomson scattering diagnostics. The experimental data show agreement with non-LTE radiation-hydrodynamic calculations of the averaged Au charge state and electron temperatures. These findings are consistent with the successful integrated modeling of the hohlraum radiation fields. Comparisons with detailed synthetic spectra calculations show that the experimental ionization distribution is slightly shifted indicating nonsteady state kinetics.
