摘要
条纹相机(包括X射线条纹相机和可见光光学条纹相机)是一种高时空分辨的诊断设备,在激光惯性约束聚变(ICF)物理实验研究中具有非常重要的应用。介绍了当今国内外激光聚变领域获得广泛应用的两种主要类型条纹相机的技术性能以及各自的技术特点,它们分别采用了同轴电极双聚焦电子光学扫描变像管和双板电极电子光学扫描管。在技术指标方面,重点论述了条纹相机动态范围的判据,分析了激光聚变实验对条纹相机动态范围的需求,介绍了当今国际上高性能条纹相机动态范围指标的现状。文章也介绍了和条纹相机发展应用相关的几项重要技术进展,这些进展包括先进光时标、抗辐射加固记录系统和抑制相机背景噪声的阴极选通技术。
The streak cameras have very important applications in Inertial Confinement Fusion(ICF),including x-ray streak cameras and optical streak cameras.At present,they are still the core diagnostic devices with the highest temporal resolution in this field.This paper introduces the performance and characteristics of two main types of the streak cameras widely used in the field of laser fusion both domestic and international.They are equipped with coaxial electrode double-focus electron optics streak tube and bilamellar electron optics streak tube respectively.In terms of specifications of streak camera,the criteria of dynamic range of streak camera are emphasized,the dynamic range data of today's international high performance streak cameras are presented.The paper also introduces several important research progresses in the development of streak camera technologies,including advanced backlighting ultraviolet fiducial system,neutron radiation tolerant device and gated cathode technology.
