A 150 kV pulsed X-ray system designed according to the bipolar charged Marx generator was introduced. Low jitter electric field-distortion switches, low inductance solid-state resistors and ceramic capacitors were used in the pulse generator to shorten the pulse risetime and width. The Marx generator was connected to the X-ray tube through the high-voltage cable. Then it can output a pulse with 100～150 kV amplitude, and drive the X-ray tube to produce a flash X-ray with 90.3×10~(-7)C/kg dose and 70 ns pulse width at 0.25 m. The X-ray system is easy to operate with stable performance and compact structure.
