Apply for Beam Time

Next Proposal Deadline

Diamond Light Source/APS Collaboration

The APS plans to issue a Call for MX beam time requests to access the Diamond Light Source.

  • Call opens: Tuesday, July 18, 2023, at 8:00 am Chicago time
  • Call closes: Monday, July 31, 2023, at 11:59 pm Chicago time
    • The Call is for Diamond AP33 Run 4 (September 6 to October 13, 2023) and AP34 Run 5 (November 8 to December 15, 2023).

Under a collaborative arrangement between the APS and the Diamond Light Source (U.K.), APS MX General Users and CATs will have access to a block of beam time on four high-throughput MX beamlines at Diamond (MX at Diamond, I03, I04, I04-1, and I24) during the APS Upgrade installation and beamline commissioning period.

The APS MX Beam time Allocation and Oversight Committee (MX-BAOC) will distribute this block of beam time at Diamond between APS General Users and CATs.

Beam time will be allocated for ONLY:

CAT members may receive time as part of their CAT's allocation from the APS for beamtime at Diamond. Please consult your CAT management.

General Users will apply THROUGH THE APS PROPOSAL PLATFORM for access to beam time at the Diamond Light Source. Below are details to consider when determining if you wish to submit a proposal for this Call. (Future calls will be offered for subsequent runs at Diamond. Check here for updates.)

  • This Call will be only for Rapid Access MX proposals through the APS.
  • Proposals will be submitted to the APS peer review process, and the APS will allocate beam time based on referee ratings.
  • Beamline assignments and scheduling for allocated requests will be managed by Diamond staff based on experimental needs.
  • For proposals that are allocated beam time, the P.I. will be contacted with additional information related to user registration with the Diamond facility, safety documentation needs, and sample shipping.

When creating your proposal in the APS Proposal System:

  • You must select the Macromolecular Crystallography Proposal (includes rapid access MC) proposal type.
  • You must select the cycle 2023-2 when filling out the beam time request; cycle selection is irrelevant to the process for proposals to Diamond.
  • Choose "Diamond Beamline (I.D.)" as the beamline choice (do not select a 2nd or 3rd choice beamline).
Additional information:
  • Users who wish to apply for beam time for Diamond through the APS will need to login with an Argonne Domain Account. 
  • To see the current Diamond Light Source run calendar go to Diamond’s web page For Users and on the right sidebar under “Quick Links” click on “Machine operations calendar.”
  • Please note that Diamond schedules beamtime on demand: data collection is scheduled AFTER Diamond receives your samples
