摘要

大画幅、高空间分辨率的条纹管是毫米空间分辨率静止图像检测系统和高光谱分辨率ICF实验的核心。本文在CST Particle Studio中建立了一种具有三同轴-圆柱形单透镜聚焦系统的大画幅条纹管，球面弯曲阴极和荧光屏模型。在静态和动态模式下，采用蒙特卡罗采样法计算并模拟了时间和空间分辨率。仿真结果表明，在整个50 mm有效阴极长度上，条纹管的静态空间分辨率可达50 lp/mm，物理时间分辨率优于45 ps，在动态工作模式下，条纹管的空间分辨率可达10 lp/mm，时间分辨率可达60 ps，仿真结果将用于指导大画幅、高空间分辨率条纹管的设计和生产。

A New Design of Large-format Streak Tube with Single-lens Focusing System

Abstract Streak tubes with large-format and high spatial resolution are central to mm-spatial-resolved STIL detection system and hyperspectral resolved ICF experiment. In this paper, we established a large-format streak tube with a three-coaxial-cylindrical single-lens focusing system, a spherically curved photocathode and phosphor screen model in CST Particle Studio. The temporal and spatial resolution were calculated and mimicked based on the Monte-Carlo sampling method in static and dynamic mode. The simulated results show that the static spatial resolution reaches 50 lp/mm over the whole 50 mm effective photocathode length, and the physical temporal resolution is better than 45 ps. Furthermore, in dynamic working mode, the streak tube can achieve spatial resolution of 10 lp/mm and temporal resolution of 60 ps. The simulation results will be used to guide the design and production for large-format with high spatial resolution streak tube development.
