Detector stand and X-ray diffraction apparatus
A detector stand for an X-ray detector is provided. A first arrangement portion arranges the X-ray detector in first orientation. A second arrangement portion arranges the X-ray detector in second orientation. The X-ray detector can be fixed to a mounting portion. In the detector stand, the X-ray detector is selectively mountable on the first arrangement portion or the second arrangement portion through the mounting portion. An arrangement angle of the X-ray detector fixed to the mounting portion is different between the first orientation and the second orientation.

in the detector stand, the X-ray detector is selectively mountable on the first arrangement portion or the second arrangement portion through the mounting portion, and
an arrangement angle of the X-ray detector fixed to the mounting portion is different between the first orientation and the second orientation.
2 . The detector stand according to claim 1 , wherein
the first orientation is landscape orientation in which a width direction of the X-ray detector extends in a lateral direction, and
the second orientation is portrait orientation in which the width direction of the X-ray detector extends in a longitudinal direction.
3 . The detector stand according to claim 2 , further comprising an adjustment portion configured to perform positional adjustment of three axes of the X-ray detector in the first orientation and positional arrangement of three axes of the X-ray detector in the second orientation.
4 . The detector stand according to claim 2 , further comprising:
a first adjustment portion including a first Y-axis adjustment mechanism configured to adjust a position of the X-ray detector in a Y direction orthogonal to an X direction that is a detection direction of the X-ray detector in the first orientation, and a first Z-axis adjustment mechanism configured to adjust a position of the X-ray detector in a Z direction orthogonal to the X direction and the Y direction in the first orientation; and
a second adjustment portion including a second Y-axis adjustment mechanism configured to adjust a position of the X-ray detector in the Y direction in the second orientation, and a second Z-axis adjustment mechanism configured to adjust a position of the X-ray detector in the Z direction in the second orientation.
5 . The detector stand according to claim 4 , further comprising an X-axis rotation adjustment mechanism configured to adjust an angle around an axis extending in the X direction of the X-ray detector, wherein
the arrangement angle of the X-ray detector fixed to the mounting portion in the first orientation is orthogonal to the arrangement angle of the X-ray detector fixed to the mounting portion in the second orientation.
6 . The detector stand according to claim 4 , wherein
the first adjustment portion includes a first X-axis rotation adjustment mechanism configured to adjust an angle around an axis extending in the X direction of the X-ray detector in the first orientation, and
the second adjustment portion includes a second X-axis rotation adjustment mechanism configured to adjust an angle around the axis extending in the X-direction of the X-ray detector in the second orientation.
7 . The detector stand according to claim 5 , wherein the first adjustment portion is provided on the mounting portion.
8 . The detector stand according to claim 7 , further comprising a coupling portion configured to be coupled to a goniometer to enable adjustment of a distance between the X-ray detector and a detection object.
