Update on Status at NSF’s ChemMatCARS, September 20, 2021
Starting September 20, 2021, all general users and visitors to Argonne facilities, who are not Argonne employees or Collaborative Access Team (CAT) operations staff, will be required to report to the Argonne Information Center (AIC).
Before site access is granted, general users and visitors must:
- attest to their vaccination status (form will be provided at the AIC)
- if not fully vaccinated, show proof of a negative COVID-19 test result that is less than 72 hours old.
Given the current state of the COVID-19 pandemic, the APS user program is currently operational to support:
- Mail-in/remote operation/participation for many capabilities. Remote and mail-in experimental access remain a priority.
- Non-Argonne user presence, permitted ONLY for experiments that have gone through a pre-approval process based on need for site access, and requiring approval of the APS Director and that have met time-sensitive and mission-essential criteria.
- An onsite user must have ANL site access, complete all APS required training courses and complete the on-site user request form. Contact email@example.com for more information.
- Non-Argonne users external to the APS should be prepared to show proof of vaccination to the beamline Point of Contact (POC) as identified on an Experiment Safety Assessment Form (ESAF) to take advantage of fully vaccinated privileges while onsite at the APS.
- Site access credentials and a corresponding prox card will be issued to named onsite users on an approved ESAF and will be valid only for the facility-approved experiment duration.
- Based on the most recent CDC guidance, all individuals regardless of vaccination status are required to wear masks and maintain six-foot social distancing while on site.
Please get in touch with the beamline contact to determine the ability of a specific beamline to support your research.
NSF’s ChemMatCARS operates three experimental stations in the areas of advanced small-molecule crystallography, liquid surface and interface scattering, and small to wide-angle scattering at the Advanced Photon Source (APS), the premier undulator-based synchrotron source of high-brilliance high-energy x-rays in the U.S.A. The instrumentation at NSF’s ChemMatCARS provides information that addresses a broad range of issues in chemistry and materials research. NSF’s ChemMatCARS is supported by the Divisions of Chemistry (CHE) and Materials Research (DMR), National Science Foundation, under grant number NSF/CHE-1834750. Construction of a second beamline at NSF’s ChemMatCARS is supported by NSF grant CHE-1836674 with contributions from the Office of Multidisciplinary Activities within the Directorate of Mathematical and Physical Sciences and NSF Divisions in Chemistry (CHE), Molecular and Cellular Biology (MCB), and Chemical, Bioengineering, Environmental, and Transport Systems Engineering (CBET).

CALL FOR PREPROPOSALS
NSF’s ChemMatCARS is seeking candidates to form partnerships for research and education in chemistry, in response to the solicitation for Partnerships for Research and Education in Chemistry (PREC), released on September 15, 2021, from the Division of Chemistry (CHE), NSF (https://beta.nsf.gov/funding/opportunities/partnerships-research-and-education-chemistry-prec). The PREC program will fund partnerships between minority-serving institutions (MSIs) and CHE-supported research centers/facilities, such as NSF’s ChemMatCARS.
