Section: claims

1. A device for switching/generating X-rays for diagnosis and curing, comprising:an electron beam generation device which accelerates a pulse electron beam to transmit the beam through a predetermined rectilinear orbit;a laser generation device which generates a pulse laser light;a laser light introduction device which introduces the pulse laser light onto the rectilinear orbit so as to collide with the pulse electron beam;a metal target which generates a particular X-ray by collision with the pulse electron beam; anda target moving device which moves the metal target between a collision position on the rectilinear orbit and a retreat position out of the orbit,wherein at the collision position, a collision surface of the metal target is positioned spatially at the same position as a collision point between the pulse electron beam and the pulse laser light,the metal target is positioned at the retreat position, and the pulse electron beam collides head-on with the pulse laser light on the rectilinear orbit to generate a monochromatic hard X-ray for diagnosis,the metal target is positioned at the collision position, and the pulse electron beam collides with the metal target to generate the particular X-ray from the same collision point, andthe X-rays for diagnosis and curing are emitted from the same light source position of the same apparatus. 2. The device for switching/generating the X-rays for diagnosis and curing according to claim 1, wherein the metal target is made of tungsten, iron, cobalt, nickel, copper, molybdenum, silver or an alloy of these metals. 3. The device for switching/generating the X-rays for diagnosis and curing according to claim 1, further comprising:a collimator which is disposed between the collision point and a person being inspected and which controls radiating directions of the monochromatic hard X-ray for diagnosis and the particular X-ray for curing. 4. The device for switching/generating the X-rays for diagnosis and curing according to claim 1, wherein the laser generation device includes a plurality of pulse laser units which generate a plurality of pulse laser beams having different wavelengths;a laser combining optical system which combines the plurality of pulse laser beams on the same optical path; anda laser control unit which controls the plurality of pulse laser units so that the plurality of pulse laser beams have a time difference therebetween. 5. The device for switching/generating the X-rays for diagnosis and curing according to claim 4, further comprising:a profile regulation optical system which regulates a beam profile of the pulse laser light at the collision point on the rectilinear orbit.
