摘要： An X-ray generator includes: a line X-ray source; a multilayer film mirror; and a side-by-side reflecting mirror including two concave mirrors joined together so as to share a join line. A cross section of a reflecting surface of the multilayer film mirror has a parabolic shape, and a focus of the parabolic shape is located at the line X-ray source. Cross sections of reflecting surfaces of the two concave mirrors of the side-by-side reflecting mirror each have a parabolic shape, and each of focuses of the parabolic shapes is located on a side opposite to the multilayer film mirror. An extended line of the join line of the side-by-side reflecting mirror passes through the multilayer film mirror and the line X-ray source as viewed in a plan view.

摘要： An X-ray optical component device having an X-ray optical component unit, a motor controller, and a connector. The connector has motor pins and motor terminals electrically connected to a motor when engaged with each other, and a signal pin and signal terminal for sensing detachment of the connector, the signal pin and signal terminal being capable of engaging with each other. A pin-side connector and a terminal-side connector are detachable. When the pin-side connector is detached from the terminal-side connector, the time that the signal pin is removed from the signal terminal is earlier than the time that the motor pins are removed from the motor terminals. During replacement of an X-ray optical component unit equipped with a motor for adjusting the position of an X-ray optical component, unwanted movement of the position of the X-ray optical component provided in the unit is prevented.

摘要： Only X-rays having a specific wavelength, selected from a group of focusing X-rays diffracted from a sample, are reflected from a monochromator based on a Bragg's condition, passed through a receiving slit and detected by an X-ray detector. The monochromator is configured to be freely removable, and arranged between the sample and a focal point at which the wavelength-selected focusing X-rays diffracted from the sample are directly focused. At this time, the monochromator is moved so as to position the monochromator as close to the focal point as possible. The monochromator comprises a multilayer mirror having an internal interplanar spacing, wherein said internal interplanar spacing varies continuously from one end of the monochromator to the other end.
