Our X-ray metrology (XRM) project team at the National Institute of Standards and Technology (NIST) works exclusively in developing Standard Reference Materials (SRMs) for the powder diffraction (PD), high-resolution x-ray diffraction (HRXRD), and X-ray reflectometry (XRR) communities. In this two-part presentation, we will present: First, our approach to making X-ray diffraction Standard Reference Materials and show how these standards help calibrate Powder diffraction instrumentation world-wide. Second, we will reveal some of the demanding aspects of establishing SI-traceability specifically how we perform femto-meter-accuracy, nano-scale measurements.
