11-BM User Program

User proposals for beamtime may request on-site experimental time or rapid-access via a mail-in program. Proposals from industrial users are also accepted.

The unique 11-BM mail-in service allows users to submit a short proposal and receive world-class powder diffraction data for their experiment typically in less than one month. This is a free service for all non-proprietary users.

To maintain a swift turnaround for all users, rapid-access allocations are limited to a single APS shift (8 hours, or 8 samples) per proposal. Experiments requiring more beamtime must submit a standard proposal via the normal APS review process (see deadlines).

Mail-in data collection is performed at a fixed energy (~ 30 keV), with limited collection at 27 keV for Sn containing samples, and users are offered a section of scans at a select number of temperatures. On-site experiments are required for more specialized measurements or for samples not acceptable for the mail-in program.

All beamtime requests must be submitted through the Advanced Photon Source General User Program. More information about 11-BM capabilities and our unique rapid-access mail-in program can be found throughout this website and on the 11-BM FAQ page.
