X-RAY GENERATION DEVICE AND X-RAY ANALYSIS DEVICE

WIPO Patent Application WO/2020/066168

A1

Provided are: an X-ray generation device that has a simple configuration and is capable of selectively generating X-rays having different wavelengths; and an X-ray analysis device. This X-ray generation device is provided with: an X-ray sealed tube including a cathode which emits thermoelectrons, and an anode which is irradiated with an electron beam obtained by the thermoelectrons being accelerated by an applied potential difference; a magnetic field generation unit which is disposed near the X-ray sealed tube so as to apply, to the electron beam, a magnetic field extending in a first direction intersecting with the traveling direction of the electron beam; and a rotational drive system which rotates the X-ray sealed tube about the center axis of the cathode and the anode, wherein on a surface of the anode, a first region is disposed on one side of a division line passing through the intersection between the surface and the center axis, and a second region is disposed on the other side, a first metal is disposed in the first region, and a second metal different from the first metal is disposed in the second region, and by the rotational drive system rotating the X-ray sealed tube, the X-ray sealed tube is disposed with respect to the magnetic field generation unit, when driven, so that the division line extends along the first direction.
