Abstract
The electron beam corresponding to radiation intensity data 112 is output from an electron source 103 by supplying high energy pulse p-1 through p-n corresponding to the radiation intensity data 112 of the radiation field to electron source 103 from power source 108. This electron beam is deflected to be incident in parallel to the medial axis of the X-ray target tube by a deflection means comprising electromagnets, X-ray beam x-1 through x-n which electron beam collides to the inner wall of X-ray target tube 104-1 through 104-n, and have desired intensity is irradiated.

An X-ray generator, comprising:
- a power source outputting high energy pulses;
- an electron source irradiating high energy electron beams by the high energy pulses;
- a microwave source supplying a high voltage microwave to the electron source;
- an X-ray source bundling up a plurality of X-ray tubes irradiating X-ray by a collision of the high-energy electron beams, arranging to continue the radiation fields of the X-ray tubes;
- a deflection means deflecting the direction of the high energy electron beams so that the high energy electron beams are incident in parallel to the medial axis of the X-ray tubes, and are incident on the X-ray tubes sequentially;
- a data setting the radiation intensity of the X-ray tube so that the predetermined dose distribution is obtained in the field of the X-ray tube;
- and
- a control means setting up the high energy pulse width according to the radiation intensity data, synchronizing a timing to output the high energy pulse and a timing to irradiate the electron beams and a timing to excite the deflection means.
