Abstract: In response to the demand for pulsed X-ray machines in the field of nuclear engineering construction, a pulsed X-ray machine was independently developed, breaking the foreign technological monopoly and achieving localization. This paper designed a pulsed X-ray tube based on a reflection structure, and integrated it with components such as batteries, high-voltage charging modules, and pulse generators to form a pulsed X-ray machine for performance testing. The test results showed that the penetration ability of the pulsed X-ray machine for steel basically reached the level of Golden XRS3.
