Not really powder diffraction, but we are all multi-faceted :-) I have recently made a number of simple x-ray Laue cameras https://neutronoptics.com/news.html#laue and customers ask about purchasing NIST standard ruby spheres for Laue camera alignment, which have long been used at ILL and other labs. https://www.nist.gov/publications/standard-reference-material-srm-1990-single-crystal-diffractometer-alignment
Anyone know where small ruby spheres suitable for Laue camera backscattering might be purchased these days ? My very best wishes to the Rietveld list participants for the end of year celebrations, and a happy and healthy New Year 2026.
