We report on what we believe to be the first use of toroidally bent crystals to record two-dimensional, spatially resolved, monochromatic images of laser-produced fusion plasmas combined with a 34-ps fast x-ray framing camera. An array of five toroidal silicon (311) and five toroidal germanium (311) crystals was developed. The imaging properties of the geometries are checked by a ray-tracing program and are compared with experimental results. The total imaging system (crystal and detector) provides an experimentally measured spatial resolution better than 15 mum. Time histories for the hydrogenlike argon emission and the heliumlike argon emission of fusion pellets driven with the GEKKO XII glass laser system are presented.
我们报告了我们认为首次使用环形弯曲晶体结合34皮秒快速X射线分幅相机来记录激光产生的聚变等离子体的二维、空间分辨单色图像。开发了一个由五个环形硅（311）晶体和五个环形锗（311）晶体组成的阵列。通过光线追踪程序检查了这些几何结构的成像特性，并与实验结果进行了比较。整个成像系统（晶体和探测器）提供了实验测量的优于15微米的空间分辨率。给出了用GEKKO XII玻璃激光系统驱动的聚变靶丸类氢氩发射和类氦氩发射的时间历程。
