摘要
设计了一种有效面积大、体积小、重量轻的多狭缝条纹变相管.通过自行编程并进行Monte-Carlo模拟计算,在离轴10 mm处,静态空间分辨率可达20 lp/mm,静态物理时间分辨率达100 ps.在电子光学设计的基础上,完成了多狭缝条纹变相管的结构设计和机械加工,通过工艺设计,制作样管,阴极有效面积达Φ22 mm.最后进行静态测试,获得了具有一定分辨能力的静态图像.该像管可以用作变相管激光雷达的探测器,实现非扫描激光三维成像.
Abstract
A new type of multi-slit streak tube was designed with large efficient area,smaller bulk and lighter weight. By programming and Monte-Carlo simulation,even 10 mm off the axis,the spatial resolution can reach to 20 lp/mm,and the static physical temporal resolution can reach to 100 ps. On the basic of theoretical design,some processes were made such as the structural design,machining and assembly. A MS-Streak tube was manufactured. Its efficient photocathode area can reach ф22 mm. After testing with static experiment system set up,a static image with certain spatial resolution was obtained.
