利用分幅相机测量铋球表面发射X射线图像
Measurement of X-ray emitted by bismuth ball using framing camera
摘要
Abstract
A kind of bismuth ball. I. E. a plastic ball coated with bismuth, has been designed to replace the conventional implosion target. The X-ray framing camera was utilized to obtain the 2D image of the reemission X-ray emitted by the bismuth ball driven by radiation. In the experiment, a branch of light was divided from the lasers, to yield the trigger signal of the camera by photoelectric conversion. The camera time scale was established by gold ball directly driven by the laser beams. According to the time scale, the time relationship of each frame of image relative to the laser beams is obtained. Analyzing the X-ray images of the bismuth ball, the ablation time of the CH film which was holding the bismuth ball and the variation of the bismuth sphere radius can be defined. The diagnostic hole's size, and the symmetry of the supporting CH film can also be inferred by the X-ray images.关键词
