Welcome to the SSRL User Research Site

Responsive Design User Portal

SSRL SPEAR shuts down for maintenance/upgrades August 2.
Operations run resume in October.

As of June 2021, SSRL is transitioning to greater on-site presence. Contact the User Office if you have questions about COVID-19 impacts on your experiments or to request an extension. Submit proposals and BTRs by posted deadlines.

Society for Science at User Facilities (SSURF)

The Society for Science at User Research Facilities (SSURF) is a non-profit organization working to advance awareness of user facility research. SSURF replaces the National User Facility Organization (NUFO) which represented the interests of scientists who conduct research at national scientific user facilities.
