Welcome to the SSRL User Research Site

User Portal

The experimental facilities at SSRL are scheduled and managed centrally to ensure that the unique resources are most fully and efficiently utilized. The facility is supported by highly motivated staff members who ensure that all visiting scientists have a productive experience. With a strong focus on serving the general scientific user community, SSRL provides access to x-ray and VUV beam lines, instrumentation, sample preparation areas, ancillary equipment and dedicated staff scientists and technicians in numerous areas.

SSRL operates approximately 9 months each year, providing more than 98% of scheduled x-ray beam time. SSRL utilizes x-rays produced by the SPEAR3 accelerator, a 3-GeV, high-brightness, third generation storage ring operating with high reliability and low emittance.

Contact our User Research Administration staff if you need additional assistance.
