SSRL Operations Update

SSRL is preparing to restart SPEAR and resume user operations for FY2024. The schedule for November-January will be posted over the coming weeks, then users can view and accept beam time assignments in the user portal.

Supporting the User Community

Visiting scientists ("users") from universities, industries and laboratories around the world use SSRL experimental facilities to conduct experiments across a broad range of scientific, engineering, and environmental disciplines.

Our Experimental Facilities

Click for Full Status

Users conduct experiments at SSRL's approximately 30 experimental stations, which utilize extremely bright x-rays produced by the SPEAR3 storage ring. SSRL provides access to beam lines, instrumentation, ancillary equipment supported by dedicated staff scientists and technicians.

Science at SSRL

SSRL's extremely bright x-rays are used by scientists to view the nanoworld, leading to cutting-edge research in drug discovery, energy efficiency and supply, environmental remediation (toxic waste cleanup), electronics, telecommunications and manufacturing.
