摘要: 根据神光-Ⅲ激光器的运作方式和靶室结构,成功研制出用于神光-Ⅲ激光器装置的X光双通道单分幅相机系统。该相机系统主要由针孔成像组件、MCP选通技术型分幅相机和科学型可见光CCD三部分组成,同时系统具有线下瞄准、线上三维调节的功能。系统中针孔直径为10 m,放大倍率为5,分幅相机单画幅宽度13 mm,长度36 mm,曝光时间0.5~10.0 ns可调。在神光-Ⅲ主机装置上成功完成了对此系统的性能考核,结果表明,该系统完全能够应用于神光-Ⅲ装置上,而且与传统方式上的针孔成像组件配接X光CCD组成的成像系统相比,具有更好的信噪比和空间分辨。Abstract: According to the operation mode and target chamber structure of SG-Ⅲ laser facility, a single frame X-ray framing camera system with double channels is successfully designed. The imaging system mainly consists of a pin-hole camera, a gated MCP framing camera and a scientific grade visible light CCD. The pin-hole diameter is 10 m, the and magnification is 5. The single frame format of the system is 13 mm36 mm, and exposure time is adjustable from 0.5 ns to 10 ns. Performance evaluation is conducted on SG-Ⅲ laser facility, and the results show that the system completely meets the requirement of SG-Ⅲ laser facility. Compared to the traditional X ray imaging system, which mainly consists of pin-hole camera and X-ray CCD, the signal-to-noise ratio and spatial resolution are better.
