摘要
参考“天蝎-Ι”原型机,重新设计了1 MV X光机系统,根据技术指标可靠性要求,对Marx发生器、场畸变开关、脉冲传输线、脉冲形成线及二极管等进行了可靠性设计。针对新设计的1 MV X光机系统,对其可靠性进行了实验研究,包含1 MV X光机系统的时间抖动和出光剂量稳定性等,根据调试实验结果制定1 MV X光机系统操作规程,按照规程对1 MV X光机系统进行了可靠性考核,连续工作81发次,最大时间抖动为146 ns,剂量为0.75~1.40 R @1 m,满足总体技术指标要求,可靠度达到98%。
Abstract
Referring to the Scorpio-1 prototype, the 1 MV X-ray system for radiography was redesigned. According to the reliability requirements, it has a reliability design of the system elements, including Marx generator, field distortion switch, pulse forming line, pulse transmission line and rod-pinch diode. Moreover, the experimental tests on the reliability of the system, including time jitter and stability of X-ray, were performed. According to the experimental results, the system operates stable and continuous outputs more than 81 shots. The following technical parameters of the system were achieved: time jitter less than 146 ns, X-ray dose 0.75?1.40 R at 1 m right in front of the system and reliability up to 98%.
