Abstract: To provide an X-ray generator capable of preventing electric corrosion and exerting stable performance over long periods. The X-ray generator includes: a rotary anticathode having a rotary anticathode part and a shaft part; an anticathode accommodating case including an air-tight case part for keeping an area surrounding the rotary anticathode part in a vacuum atmosphere, and a journaling case part for rotatively supporting the shaft part via a bearing; and an electric motor to rotatably drive the anticathode (target). A water-cooled jacket, through which cooling water for cooling the rotary anticathode part and the shaft part flows, is provided in the rotary anticathode.

Abstract: To solve a difference in an emitting directions by switching the types of X-rays. An X-ray generator comprises: an anticathode unit 3 in which a plurality of anticathode parts 2 (2A and 2B) that emit X-rays by collision of thermoelectrons are disposed side by side; a cathode 4 for releasing the thermoelectrons toward the anticathode parts 2A and 2B on the anticathode unit 3; and a cathode moving mechanism that switches the anticathode parts, against which the thermoelectrons from the cathode 4 collide by moving the cathode 4 along the diction of aligning anticathode parts 2A and 2B.

Abstract: In an X-ray diffractometer that reads an X-ray diffraction image by storing and recording the image on a stimulable phosphor, it is possible to realize higher speed of a series of process operations of exposure—read—erase relatively easily and also realize simplification and a small size of a constitution of the diffractometer. The X-ray diffractometer stores and records an X-ray diffraction image on an imaging plate 40 formed of a stimulable phosphor. The imaging plate 40 is installed on a predetermined exposure stage, an eraser 60 is installed behind the imaging plate 40, and a Tear side of an area where the image is stored and recorded is made light transmissive. Whereby, the eraser 60 conducts erasing operation in the area where the image is stored and recorded by irradiating a rear surface of the imaging plate 40 with an erasing light.
