Quick Guide for New Users

Prior to Registering as a new user:

  • When considering experiments at NSF’s ChemMatCARS facility, we strongly encourage you to contact ChemMatCARS staff and discuss feasibility of your experiments.
    Please contact the scientist from the appropriate experimental technique Contacts lists to the right of this page.
  • You can find general information about our beamlines and other ChemMatCARS facilities here:
  • All ChemMatCARS users have to submit their proposals through the APS General User Program (GUP).
    Be sure to review the criteria for general user proposals (GUP) and proposal FAQ.

Brief summary for new users:

Be sure to follow the APS New User Checklist

  • You need to register as an APS user and submit a proposal in order to apply for ChemMatCARS beamtime.
  • Your home institution has to have an User Agreement with APS.  Please follow instructions on that page to check for existing agreement or for establishing a new agreement.
  • An APS proposal is considered standard if submitted before the APS deadline for a run cycle and Rapid Access if submitted after the deadline.  You can find more information about proposal submission and review here.
  • Using your active APS proposal, you have to submit a beamtime request (BTR) for each APS run cycle.  You can use your active proposal to submit BTRs for several APS run cycles if needed for your project.
  • Following beamtime allocation process, you will be contacted and informed if beamtime has been allocated for your proposal.
  • If beamtime has been allocated, ChemMatCARS staff will contact you about scheduling your beamtime.
  • Before your visit, you have to complete the APS user safety training, complete Experiment Safety Assessment Form and notify APS of your arrival by using the Gate Pass Request tab in My APS Portal.
  • You can find your APS user information at My APS Portal.  More useful links for users can be found on the APS User Information.
  • When your work is published, Send the Publication to the APS with a copy to Natalie Chen. Please include the NSF’s ChemMatCARS Acknowledgment Statement in your publications:

NSF’s ChemMatCARS Sector 15 is supported by the Divisions of Chemistry (CHE) and Materials Research (DMR), National Science Foundation, under grant number NSF/CHE- 1834750. Use of the Advanced Photon Source, an Office of Science User Facility operated for the U.S. Department of Energy (DOE) Office of Science by Argonne National Laboratory, was supported by the U.S. DOE under Contract No. DE-AC02-06CH11357.

Please Note: “ChemMatCARS” has changed to “NSF’s ChemMatCARS”. Please acknowledge “NSF’s ChemMatCARS” in publications.

Brief summary for returning users:

  •  Apply for Beamtime
  • Submit an updated APS User Registration Form as a “returning user” to provide your current information. Non-U.S. citizens with expired or expiring security clearance are encouraged to re-register with the APS as soon as possible.
  • Make sure all your required training is current by contacting:
  • Complete any expired training Remotely, or contact the APS User Office or Natalie Chen to schedule on-site training.
  • Once beamtime has been allocated and ChemMatCARS has contacted you with dates, complete an Experiment Safety Assessment Form (ESAF) via the link sent in your confirmation letter or by logging in to the APS Scheduling System. Complete the ESAF at least 10 business days before your visit. The ESAF must be approved by both NSF’s ChemMatCARS and APS safety personnel before you can begin work.
  • When your work is published, Send the Publication to the APS with a copy to Natalie Chen. Please include the NSF’s ChemMatCARS acknowledgment statement in your publications:

Aps User Portal

You can use the APS User Portal as your primary access gateway to several APS user systems. From the portal, you can update your biographical information, check in to let APS User Office know the arrival /departure times for your next visit, review the status of your required training and update it remotely, ensure that your APS access permission is current, sign a user agreement acknowledgement form, and send messages to the User Office and your beamline contact.”
