We demonstrate the use of three diagnostic tools which simultaneously view the target from nearly the same direction, and their results are combined to provide temporally, spectrally, and spatially resolved absolutely calibrated target emission information. To demonstrate this capability, Au targets were irradiated by 1.8 kJ, 3 ns laser pulses to produce broadband soft x-ray emission in the 0.1-3.5 keV spectral range. Target diagnostics included a time-resolved x-ray diode array, each measured a partial spectral band, time-integrated spectrally resolved absolutely calibrated transmission grating spectrometer, and static and time-resolved soft x-ray imagers coupled to a charge-coupled device camera and to a streak camera, respectively, measuring spatially and temporally resolved radiation at the main Au target emission bands. The combined temporally, spectrally, and spatially resolved absolutely calibrated target emission result can be compared to simulations and be used to design and analyze experiments in which the source emission is used as a drive for various physical processes.
我们展示了三种诊断工具的使用方法，它们能从几乎相同的方向同时观察目标，并将其结果相结合，以提供时间、光谱和空间分辨的绝对校准目标发射信息。为证明这一能力，用1.8千焦、3纳秒的激光脉冲照射金靶，以在0.1 - 3.5千电子伏光谱范围内产生宽带软X射线发射。目标诊断包括一个时间分辨X射线二极管阵列，每个阵列测量部分光谱带；时间积分光谱分辨绝对校准透射光栅光谱仪；以及分别与电荷耦合器件相机和条纹相机耦合的静态和时间分辨软X射线成像仪，它们在金靶的主要发射波段测量空间和时间分辨的辐射。时间、光谱和空间分辨的绝对校准目标发射的综合结果可与模拟结果进行比较，并用于设计和分析实验，在这些实验中，源发射被用作各种物理过程的驱动。
