在温度T =(72±4)eV下测量了150 ~ 1200 eV光子能量范围内的铁等离子体吸收光谱。用铝与铁混合的吸收光谱诊断了电子温度。密度不是直接诊断的，而是用Multi-1D代码从辐射流体动力学模拟中获得的。较宽的光子能量范围使我们能够同时观测在该温度下主导辐射输运的l壳层和m壳层跃迁。将光谱解析的传输数据与详细配置计算模型的计算结果进行了比较，发现了合理的一致性。
Measurements of iron-plasma absorption spectrum over 150–1200 eV photon energy range were reported at temperature T = (72 ± 4) eV. The electron temperature was diagnosed with the absorption spectrum of aluminum mixed with iron. The density was not diagnosed directly but obtained from a radiative hydrodynamic simulation with the Multi-1D code. The broad photon energy range enables simultaneous observation of the L-shell and M-shell transitions that dominate the radiation transport at this temperature. The spectrally resolved transmission data were compared to the detailed-configuration-accounting model calculations and reasonable agreement was found.
