Rotating anticathode X-ray generating apparatus and X-ray generating method

Abstract

A rotating anticathode X-ray generating apparatus, includes: a rotating anticathode; an electron beam source for irradiating an electron beam onto the rotating anticathode so that an irradiating direction of the electron beams is set equal to a direction of a centrifugal force caused by a rotation of the rotating anticathode; and a first material for forming a film so as to cover at least an electron beam irradiating portion of the rotating anticathode and to suppress an evaporation of a second material making the rotating anticathode from the electron beam irradiating portion, wherein the first material is disposed in a path of the electron beam so that the first material is configured so as to be converted into the film through an irradiation of the electron beam.
