新型闪光X射线设备设计方案

本文叙述了我们正在研制的新型闪光X射线设备的设计方案。其主要特点是:(1)毫微秒脉冲发生器采用组件式结构与美国Hewlett-Pac ard公司的产品相似,(2)减少了Marx发生器回路的电感,可提高闪光X射线设备的输出电压及减少设备的体积,(3)采用多级触发,扩展了球隙开关的触发工作范围,(4)采用多尖阴极的爆炸发射闪光X射线管,增加了闪光X射线管的输出剂量及寿命。 改进后的设备,将达到和部份超过美国Hewlett-Packard公司产品的性能。

DESIGN OF A MODERN FLASH RADIOGRAPHY SYSTEM

In this article we describe the project of a Modem Flash Radiography System being constructed by our institute .Its main characters are:(1), The Marx generator for nanosecond puke has mo-dular construction,similar to products of Hewlett-Packard Company of American,to improve the stability .(2),The inductance of the Marx circuit has been reduced,so the output voltage of this Flash Radiography System will be raised and its volume will be reduced.(3),Multi-stage triggers have been used,whhich will extend the trigger range of gap switch.(4),Flash X-Ray Tube with multi-dp explosive cathode have been manufactured,it will improve dose and life of Flash X-Ray Tube.The performances of this improved equipment will catch up with and partially surpass the performances of products of Hewlett-Packard Company.
