Welcome to the 11-BM Homepage
Beamline 11-BM is a dedicated powder diffraction instrument at the APS. It offers the highest resolution powder diffraction data available in the Americas. Learn how powder diffraction could be be used in your research.
Proposals for both on-site experiments or mail-in access are accepted. New users, or those with a limited number of samples, should consider 11-BM's unique rapid-access mail-in program.
11-BM combines the brilliance of an APS bending magnet source with the efficiency of a sagittally focused double-crystal Si monochromator to achieve world-class sensitivity and resolution.
The diffractometer uses multiple single-crystal analyzer detectors to simultaneously offer high-speed (≤ 1 hr) and high-resolution (< 1.4 x 10-4 ΔQ/Q) data collection.
Learn more about the 11-BM user program and access for
industrial users, explore the instrument's design and performance, read about science performed at the beamline, and browse powder diffraction resources.
The APS operates two dedicated powder diffraction beamlines. Find more information on the
