Apply for Beam Time

Next Proposal Deadline

General User Proposal Call Cycle 2024-3

Submission Deadline: June 28, 2024

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 2024-3 cycle (October - December 2024) is soliciting proposals for possible experiments that will be considered based on each beamline's individual schedule and capabilities. Proposals submitted to this call will be valid for 2 years (6 cycles) or until the PRP-recommended shifts are used up. Submission of a request for time is not a guarantee of allocation.

Proposal types that will be accepted for this call include:

  • General User - Regular
  • General User - Macromolecular Crystallography
  • Resource Staff (includes CAT and APS staff)

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
