Apply for Beam Time

Next Proposal Deadline

General User Proposal Call 2025-1 has closed.

As the APS accelerator and storage ring return to operations, beamlines around the facility will begin to resume their user programs. The timelines for bringing users back will vary beamline to beamline. 

This call for the 2025-1 cycle (January - April 2025) will be soliciting proposals for possible experiments that will be considered based on each beamline's individual schedule and capabilities.

Proposal types that will be accepted for this call include:

  • General User - Regular
  • General User - Macromolecular Crystallography
  • eBERlight - Macromolecular Crystallography
  • Resource Staff (includes CAT and APS staff)
  • CAT Member
  • Partner User Proposal
  • 2024-3 Rapid Access

Information about the specifications and capabilities of the post-Upgrade beamlines can be found in the APS Beamline Directory. PIs are encouraged to contact beamline scientists for more detailed information on the status and current capabilities of the beamlines.

Note: Only those beamlines that feel they will be ready to support general users will be available to select in your request for beam time in the Universal Proposal System.
