| 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; and
a 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, and
the X-rays for diagnosis and curing are emitted from the same light source position of the same apparatus.
