Update on Status at NSF’s ChemMatCARS, January 12, 2021
Given the current state of the COVID-19 pandemic, the APS user program is currently operational to support:
- Mail-in/remote access work for any research involving low-risk samples and most medium-risk samples as defined on the Experiment Safety Assessment Form.
- Experiments proposed by users with prior APS experience that cannot be performed remotely and that meet specific criteria. These proposals will be considered on a case-by-case basis with no guarantee of approval. Contact email@example.com for more information.
Please get in touch with the beamline contact to determine the ability of a specific beamline to support your research.
Onsite access remains prohibited for external users for majority of beamlines at APS, including ChemMatCARS beamline. Please see the announcement on the APS home page or the User Info During the COVID Pandemic page.
Beamline scientist contacts: Dr. Yu-Sheng Chen, Dr. Wei Bu and Dr. Mrinal Bera.
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).

In conjuction with the 2021 APS/CNM Users Meeting, NSF’s ChemMatCARS is offering a two-day school on data analysis for X-ray studies of liquid interfaces. The school is designed primarily for graduate students, postdoctoral researchers and young scientists with some expertise in liquid interface science. The registration is open.
