A new generation of fast-gated x-ray framing cameras have been developed that are capable of capturing multiple frames along a single line-of-sight with 30 ps temporal resolution. The instruments are constructed by integrating pulse-dilation electron imaging with burst mode hybrid-complimentary metal-oxide-semiconductor sensors. Two such instruments have been developed, characterized, and fielded at the National Ignition Facility and the OMEGA laser. These instruments are particularly suited for advanced x-ray imaging applications in Inertial Confinement Fusion and High energy density experiments. Here, we discuss the system architecture and the techniques required for tuning the instruments to achieve optimal performance. Characterization results are also presented along with planned future improvements to the design.
新一代快速门控X射线分幅相机已经研制成功，它能够以30皮秒的时间分辨率沿单一视线方向捕获多帧图像。这些仪器是通过将脉冲扩展电子成像与突发模式混合互补金属氧化物半导体传感器集成而构建的。已经研制出两台这样的仪器，并在国家点火装置和欧米茄激光器上进行了表征和实地测试。这些仪器特别适用于惯性约束聚变和高能量密度实验中的先进X射线成像应用。在这里，我们讨论了系统架构以及调整仪器以实现最佳性能所需的技术。还给出了表征结果以及对该设计计划中的未来改进。
