Abstract: An X-ray generating apparatus includes an X-ray generating tube including an electron gun and a target configured to generate X-rays upon receiving an electron beam emitted from the electron gun, a deflector configured to deflect the electron beam, a driving circuit configured to apply an accelerating voltage between a cathode of the electron gun and the target, and an adjuster configured to adjust deflection of the electron beam by the deflector in accordance with the accelerating voltage or an amount of change in the accelerating voltage so as to reduce a change in incident position of the electron beam onto the target due to a change in the accelerating voltage.

Abstract: An X-ray generating apparatus includes an electron gun, a target configured to generate X-rays by being irradiated with an electron beam emitted from the electron gun, and a controller configured to control a first mode for thinning the target by irradiating the target with an electron beam with a current adjusted within a first current range and a second mode for generating X-rays by irradiating the target with an electron beam with a current adjusted within a second current range. The first current range has a lower limit larger than an upper limit of the second current range.

Abstract: An ion gun according to one embodiment of the present invention has an anode, a cathode having a first portion and a second portion that face the anode, and a magnet that creates a spatial magnetic field between the first portion and the second portion. An annular gap including a curved portion is provided between the first portion and the second portion of the cathode. The magnet creates lines of magnetic field having the bottom inside with respect to the sectional center line of the gap between the first portion and the second portion of the curved portion.

Abstract: Atomic diffusion bonding is carried out using a bonding film comprising a nitride formed at a bonding surface. Operating in a vacuum chamber, a bonding film comprising a nitride is formed on each of flat surfaces of two substrates that each have the flat surface, and, by overlapping the two substrates so the bonding films formed on the two substrates are in contact with each other, the two substrates are joined by the generation of atomic diffusion at a bonding interface between the bonding films.

Abstract: An X-ray generation device includes a cathode including an electron source generating an electron beam, an anode including a target to transmit an X-ray generated by collision of the electron beam, and a convergence electrode converging the electron beam toward the target. The target has a first region having a locally small thickness and a second region having a larger thickness than the first region. The X-ray generation device further includes a deflection unit to switch an incident position of the electron beam between the first region and the second region. The deflection unit has an adjustment mode to adjust an X-ray focal spot diameter and an X-ray generation mode to generate an X-ray, the electron beam is caused to enter the first region in the adjustment mode, and the electron beam is caused to enter the second region in the X-ray generation mode.
