General User Proposals for 11-BM
Requests for measurements or beamtime at 11-BM must be submitted as a General User Proposal (GUP)
. Register with the APS User Office
to obtain a badge number needed to access the GUP system.
Rapid Access mail-in requests may be submitted at any time, and are typically reviewed within ~ 1 week of submission.
On-Site experiment requests should be submitted for one of the three annual APS proposal deadlines. Check the APS Proposal Calendar
for exact dates.
Beamtime is requested in units of time called "shifts", where 1 shift is 8 hours (3 shifts per day). Currently 11-BM reserves ~ 50% of available shifts for rapid access mail-in measurements.
