提出了一种基于电子直线加速器的高能密度物质三个正交方向的动态电子束成像方案。通过对散射电子束在靶中的成像，可以获得靶的轮廓、密度等动态信息。使用具有灵活时间结构的电子束团串，可以实现非常高的时间演化。在该方案中，在一个实验事件中可以获得10 10帧/秒，时间分辨率可以达到1 ps，空间分辨率达到1 µm。这一概念的成功演示将对未来的惯性约束聚变科学和HED物理研究产生重大影响。
We present a scheme of electron beam radiography to dynamically diagnose the high energy density (HED) matter in three orthogonal directions simultaneously based on electron Linear Accelerator. The dynamic target information such as, its profile and density could be obtained through imaging the scattered electron beam passing through the target. Using an electron bunch train with flexible time structure, a very high temporal evolution could be achieved. In this proposed scheme, it is possible to obtain 10 10 frames/second in one experimental event, and the temporal resolution can go up to 1 ps, spatial resolution to 1 µm. Successful demonstration of this concept will have a major impact for both future inertial confinement fusion science and HED physics research.
