X-RAY LASER GENERATOR WITH HIGH INTENSITY ELECTRON GUN AND GENERATING METHOD THEREOF

PURPOSE:To enable formation of a laser from X-ray in an X-ray laser generator having a high intensity electron gun in a vacuum container and paired cathodes receiving an electron beam from the gun by forming a conical cavity at the cathodes and emitting a beam to the bottom of the cavity. CONSTITUTION:A high intensity electron gun 1 is arranged at one end of a vacuum container 6, is confronted with an electron beam 2 emitted from the gun 1, paired cathodes 3 are provided, a vacuum exhaust port 7 is used, and the container 6 is evacuated in high vacuum. In this structure, an incident port 4 having a hole confronted with the gun 1 is formed at the cathode 3, an X-ray emitting hole 5 continued to the port 4 is formed, and laser X-ray is emitted from the hole 5. At this time, the diameter of the port 4 is less than approx. 0.2mm., is directed toward the port 5, and hence toward the end of the conical cavity, and is inclined at approx. 5 deg. while throttling to 1/10 of the diameter. In this manner, the X-ray laser can be formed.
