摘要
获取高时空分辨的M带X射线辐射能流信息是黑腔物理研究的重要内容之一,条纹相机平响应存在谱响应耦合、谱改造元件结构设计等问题。通过对条纹相机和透射式X射线光阴极谱响应特性的研究,提出组合滤片调制法以实现条纹相机M带带通平响应。计算表明,在M带能区内谱灵敏度不平整度仅为2.7%,带通效果良好。
The diagnosis of X-ray flux with high temporal and spatial resolutions is important in the researches of hohlraum physics, and spectral response coupling and design of spectrum rebuilding unit are key issues in the design of flat-response streak camera. Based on the study of the spectral response characteristics of streak camera and X-ray transmission photocathode, compound filter is adopted to realize the M-band band-pass flat-response of streak camera. The calculation shows that the flatness of spectral response is better than 2.7% with an acceptable band pass effect.
