摘要
基于快前沿Mini-Marx发生器拓扑结构和冷阴极反射靶真空X射线二极管一体化设计研发出了紧凑型便携式150 kV闪光X光源系统。介绍了设计的Mini-Marx发生器和闪光X光二极管，给出了相应的实验结果。该闪光X光源系统获得了距光源25 cm处剂量大于7.7×10-6 C/kg、1 m处穿透铝大于60 mm、焦斑1~3 mm可调的闪光X射线。该闪光X光源和成像单元组成的闪光照相具有系统体积小、运行可靠的特点。
Abstract
A portable 150 kV flash X-ray system based on fast rise time mini-Marx generator principle was designed in coaxial structure. The experimental results of a 10-stage 150 kV Mini-Marx generator and flash X-ray tube were described. With a flash X-ray tube integrated directly into the Mini-Marx generator as a load, the formed flash X-ray system generated a dose of 77×10-6 C/kg at 25 cm away for flash X-radiography. It penetrated aluminium 60 mm in thickness with source size 1-3 mm.
