More attention has been paid to detecting X-ray from gas breakdown under HV nanosecond pulse both at home and ahroad in order to explore the runaway behavior of high-energy electrons and discharge mechanism during the breakdown process. In this paper, the generation and detection methods of the X-ray are introduced, and the progress in detection experiments of X-ray from gas breakdown under HV nanosecond pulse is reviewed. Moreover, the detection apparatus, the main conclusions, the influence factors on detection and the corresponding solutions are analyzed to facilitate further researches on gas breakdown mechanism under HV nanosecond pulse.
