X-ray generator and x-ray analysis device

An X-ray generator comprising:

• a line X-ray source for emitting an X-ray beam in a first direction, the line X-ray source being elongated in a second direction perpendicular to the first direction, the X-ray beam being elongated in the second direction;
• a multilayer film mirror for reflecting and collimating the X-ray beam;
• and
• a side-by-side reflecting mirror for reflecting and focusing the X-ray beam collimated by the multilayer film mirror, the side-by-side reflecting mirror including two concave mirrors joined together so as to share a join line, wherein:
• 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, the reflecting surface is configured to keep the X-ray beam elongated in the second direction;
• and
• 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, the reflecting surfaces are configured to make the elongated X-ray beam point-focused.
