PURPOSE:To enable X-rays to be fully taken out by dropping a liquid metal on a target and focusing and radiating laser light on liquid drops of this liquid metal for generating X-rays. CONSTITUTION:When a liquid metal 13 such as Hg and Ga is dropped from a liquid metal supply port 12 at a rate of about 3-10 times per sec and thereon laser light 15 is focused and radiated, plasma 17 in form of radiation is generated in this part so as to generate thereby X-rays. At this time, a metal plate 11 is provided on the rear wall of the liquid metal 13 so that explosion at the time of plasmatic transformation is intercepted by the metal plate 11 so that it may not be generated in its rear wall direction but in its front wall direction. Here, a metal target is the liquid metal 13 so that a molten metal being atomized and scattered at the time of plasmatic transformation becomes liquid so as not to continue to be stuck to the inside wall of a vacuum chamber and the liquid metal 13 hitting the inside wall and flowing in is collected from a collection port 14. Accordingly, the problem, in which a metal is stuck to an X-ray taking-out window so as to be unable to fully lead out X-rays as in a conventional case, does not arise. |
