| 摘 要： | 针对在阳加速器上进行的Z箍缩内爆实验所要求的超快分幅摄影技术研究,主要利用八个微通道板构成摄影系统的快门以达到时间分辨的要求,同时解决了在阳加速器上的精密同步问题以使系统可以稳定、可靠地一次拍摄到八幅图像,图像间隔最小为10 ns,曝光时间可达到3 ns.该技术以分幅原理获得大幅面的图像数据,具有图像特征清晰、空间信息详细的特点,为Z箍缩过程的研究提供了翔实的实验数据.

| Abstract: | A time-resolved framing photography has been set up,which characterizes exposure time of about 3ns and interframe time of 10ns.It can capture up to 8 frame images at once.The technology is a combination of high speed electronics,image intensifier technology and optical splitter technology.The shutter in the system are structured by 8 MCPs and the time-resolved desire can be met by controlling the shutters sequentially.The images captured by this time-resolved framing photography characterize high definition,abundant spatial information.The evolutive course of Z pinch imploding plasma has been recorded clearly and the latest results will be displayed. |
