Abstract

An environmentally controlled sample stage for Scintag's six-position XRD sample changer is described. Unlike the commercial environmental stages for Scintag XRD units which require removal of the sample changer, and installation and alignment of the sample stage, the stage described herein is designed to fit directly on the sample changer with no realignment. Such a stage provides for more convenient operation for an X-ray diffractometer with multiple users in both routine (ambient environment) and nonroutine (nonambient temperatures up to 250 °C and varying relative humidities) modes. In addition, the new stage uses a window made of a material that is safer to machine compared to beryllium (which is toxic).
