![]() X-ray diffraction results of two NIST standards LaB 6 and α-Al 2O 3 as well as five actinide dioxides ThO 2, UO 2, NpO 2, PuO 2 and AmO 2 are presented to show the efficiency of the setup. Ultimately, keeping the diffractometer out of a glove-box also limits the volume of the final nuclear wastes, and thus the removable sample stage is the only `active' part. The device was developed to avoid an expensive and time-consuming nuclearization of the diffractometer while also keeping it easily accessible for maintenance. No preliminary decontamination and/or decontainment of the sample is necessary. would like a zero-background XRD sample holder for our Rigaku Miniflex. ![]() The whole setup is thus hermetically unplugged from the glove-box and positioned on the centre of the goniometer. ![]() The setup consists of a removable, fully hermetic sample stage, with a 200 µm-thick beryllium window, that can be plugged onto a glove-box, allowing the sample to be introduced in an hermetic medium that also encapsulates the glove-box atmosphere throughout the analysis process. ![]() A new sample stage for characterizing radioactive materials by X-ray powder diffraction was developed at the ATALANTE facility (CEA Marcoule, France) using a conventional (non-nuclearized) Bruker D8 goniometer mounted in Bragg–Brentano geometry. ![]()
