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:

NIST SRM Certificates (with lattice values etc) are available for download here:

Lanthanum Hexaboride (LaB6), NIST SRM 660a

Silicon (Si), NIST SRM 640c

Empty 11-BM Kapton sample capillary

11-BM background, air scatter only (no sample)

Note: exact background shape for 2θ < 2° may vary due to beamstop positioning. Contact 11-BM staff with questions.

Instrument Parameter and Input Files

GSAS

On-site and Mail-in users requesting GSAS format data will receive an appropriate .prm parameter file with their data.

When using the example .prm files with SRM data above, manually modify the wavelength in the .prm file as needed.
