A high-intensity igic flash x-ray generator with a hot cathode radiation tube for biomedical radiography is described. This generator consisted of the following components: a highvoltage power supply, a coaxial oil condenser of 0.15μF-120kV, a low-impedance transmission line, a turbo molecular pump, and a flash x-ray tube having a hot cathode. The x-ray tube was of the diode type which was connected to the turbo molecular pump. The pulse condenser was charged from 40 to 120kV by a high-voltage power supply, and the electric charges were discharged to the x-ray tube by an impulse switching system. The pulse widths of the x-ray output were about 50ns, and the x-ray intensities were less tha 2.44μC/kg at 1m per pulse. The effective focal spot size was determined by the diameter of the anode tip and ranged from 0.5 to 3.0mm in diameter.
