APS Operations and General User Programs During the COVID Pandemic

While onsite access remains prohibited for many, the transition to limited operations announced on June 15 to allow for a select number of additional experiments to take place continues. 

The APS user program is currently operational to support:

  • Research on SARS-CoV-2 or other COVID-19 related research that addresses the current pandemic.
  • Critical, proprietary pharmaceutical research.
  • Mail-in/remote access work for any research involving low-risk samples and most medium-risk samples (as defined on the ESAF form).
  • Limited in-situ research (set-up with one person, and ability to carry out majority of experiment safely remotely)

The links below should provide you with details to submit a general user or COVID proposal and other important links.  For administrative assistance, please contact the APS User Office at For technical assistance on COVID proposals, please contact Bob Fischetti at
