Standard Reference Materials

Details of powder diffraction data measured at 11-BM for standard reference materials are listed below and are available in several formats. These are periodically updated. Contact 11-BM staff with questions.

Data are typically measured at ~ 30 keV under ambient conditions. Check the file header for full details and scan parameters.

More information about 11-BM data collection and data formats can be found here:

Instrument Parameter & Input Files for 11-BM

GSAS: Instrument Parameter Files Instrument parameter files (.prm) for current and past 11-BM run cycles are available here. Note, mail-in users requesting GSAS format data will receive an appropriate .prm parameter file with their data. When using the example .prm files below, manually modify the wavelength as needed.
