The 11-BM diffractometer has 12 analyzers and offers simultaneous high-speed (<= 1 hr) and high-resolution (~1.4 x 10^-4 ΔQ/Q) data collection. Users can access the instrument via mail-in access or can submit proposals for on-site use.

Mail-in collection is performed with select scan conditions at a fixed energy (typically ~30 keV). Rapid access mail-in users are limited to 8 samples or 8 hours (1 shift).

Users may submit a standard (non-rapid access) proposal requesting beam time for work that cannot be accomplished under the mail-in service.
