Abstract
A rotating anticathode X-ray generating apparatus which is configured such that an X-ray is generated by an irradiation of an electron beam emitted from a cathode includes a rotating anticathode with an electron beam irradiating portion to generate the X-ray through the irradiation of the electron beam so that a direction of the electron beam is set equal to a direction of a centrifugal force caused by a rotation of the rotating anticathode; and a film for covering at least the electron beam irradiating portion so as to prevent an evaporation of a material making the rotating anticathode.

A rotating anticathode X-ray generating apparatus which is configured such that an X-ray is generated by an irradiation of an electron beam emitted from a cathode, comprising:
- a rotating anticathode with an electron beam irradiating portion to generate said X-ray through said irradiation of said electron beam so that a direction of said electron beam is set equal to a direction of a centrifugal force caused by a rotation of said rotating anticathode;
- and
- a film for covering at least said electron beam irradiating portion so as to prevent an evaporation of a material making said rotating anticathode.
A method for generating an X-ray by irradiating an electron beam from a cathode, comprising the steps of:
- forming an electron beam irradiating portion on a rotating anticathode so that a direction of said electron beam is set equal to a direction of a centrifugal force caused by a rotation of said rotating anticathode, thereby generating said X-ray;
- and
- covering at least said electron beam irradiating portion with a film so as to prevent an evaporation of a material making said rotating anticathode.
