Patent ID: 7645994

Claim:
A device of outputting high and/or low energy X-rays, comprising a control system, an electron gun power supply, a high-voltage electron gun power supply, a microwave power source, an electron linear accelerating tube, a high-voltage electron gun and a radiation target, wherein the electron gun power supply powers the electron linear accelerating tube under the control of the control system; the microwave power source accelerates electron beams generated by the electron linear accelerating tube under the control of the control system; the electron linear accelerating tube is connected to the electron gun power supply and the microwave power source respectively, to generate high energy electron beams; the high-voltage electron gun power supply powers the high-voltage electron gun under the control of the control system; the high-voltage electron gun is connected to the voltage electron gun power supply to generate low energy electron beams; the radiation target accepts the high energy electron beams to generate high energy transmission X-rays, and accept the low energy electron beams to generate low energy reflection X-rays; wherein the high-voltage electron gun is provided with a transmitting tube for the low energy electron beams, which has an X-ray output window a radiation direction of the high energy transmission X-rays is the same as that of the low energy reflection X-rays.
