User Resources

Prior to Registering as a new user:

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

Brief summary for new users:

Be sure to follow the Advanced Photon Source (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 a User Agreement with APS. Over 1400 institutions have agreements. Check for an existing agreement first, then if your institution is not on the list, follow the directions for beginning the process of 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.  More information about proposal submission and review.
• APS run cycle. You can use your active proposal to submit BTRs for several APS run cycles if they will be needed for your project.
• Following the 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 the 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 ChemMatCARS Acknowledgment Statement in your publications:
