Experimental research on reliability of 1 MV X-ray system for radiography

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%. (authors)
