APS Response to the Coronavirus Crisis


Argonne Extends Site Restrictions

April 2, 2020

To cooperate with the extension of the stay-at-home order issued March 31 by the Governor of Illinois, Argonne is extending the site restrictions enacted with the Governor’s original order to the end of April. The Lab has ceased all on-site functions except those deemed government critical and will continue to maximize telecommuting. The APS will remain operational to support critical COVID-19 related work and for critical remote research only. 

COVID-19 PORTAL: In light of the rapidly changing situation world-wide resulting from the COVID-19 virus, the Department of Energy (DOE) Basic Energy Sciences light sources want to ensure they are doing everything possible to enable research into this virus and the search for an effective vaccine or other treatment. The DOE supports research into structural biology in partnership with the National Institutes of Health, and universities. This portal collects relevant structural biology resources in a single location, listing their basic characteristics and a point of contact for each.

Expedited, Rapid Access Call for COVID-19 Research:

The APS continues to operate, providing expedited, remote access but only for research related to COVID-19 at this time. The Structural Biology Portal lists available APS beamlines for macromolecular crystallography and BioSAXS. Step-by-step instructions on how to apply for expedited beam time are listed on the New User Checklist. All users must be registered and their home institution must have an active User Agreement.

Please submit a Rapid Access Proposal and state that the research is related to SARS CoV-2 proteins or COVID-19.

If the requested beamline is an MX beamline, submit a Macromolecular Crystallography Proposal (choose rapid access 2020-1 for immediate work). Here is a list of MX beamlines.

If the requested beamline is NOT an MX beamline, choose Rapid Access General User Proposal and select the 2020-1 cycle for immediate work.

For administrative assistance, please contact the APS User Office at For technical assistance, please contact Bob Fischetti at

To continue to meet the needs for ongoing, remote-only COVID-19 research, APS management will extend the current 2020-1 run by two weeks – to May 12. Please see more information and the revised long-range schedule here.
