Welcome to the SSRL User Research Site

Responsive Design User Portal

SSRL is currently planning for the remainder of our 2020 run in the COVID-19 era. Contact the User Office if you have questions about how this impacts your experiments or to request an extension for impacted proposals.


    • Register in the user portal and be listed on a scheduled experiment 14 days before any planned visits (review check-in procedures).
    • Complete required online safety training before arrival onsite. (Sidebar Step 5)
    • Bring original identification documents  to the VUE Center when checking in to obtain or renew a User Badge (valid driver's license for US citizens, combination of passport and visa documents (or green card) and CV for foreign nationals. See Documents Required for Check-in at SLAC).  
    • Confirm that your institution has a User Agreement – This MUST be completed by an appropriate institution official in advance of scheduled beam time.

    Note:  Contact SSRL beamline scientists or floor support staff for other meetings or visits that do not require a user badge, or contact the URA office for assistance.

  • LODGING:  Reserve rooms at the GUEST HOUSE using the SLAC User Reservations Portal to access rooms and rates not accessible to other guests (specify SSRL, proposal number and spokesperson when making reservations through the user reservations portal).

  • FOOD:  Visit the SLACafé Monday–Friday 11:30am–2:30pm. Other FOOD OPTIONS include Starbucks and restaurants that deliver to SLAC Main Gate/Guest House.

  • NEWS:  Stay informed by subscribing to SSRL Headline News (send e-mail to with "subscribe ssrl-headlines" in the body).

  • WORK SAFELY:  Be aware and exercise caution when visiting SLAC, particularly during construction. Contact Security if help is needed or to report any problems or suspicious activity: 650-926-2551. For EMERGENCIES, CALL 911 OR 5555.

Planning Ahead Getting Beam Time



Foreign nationals must arrive at the VUE Center for check-in with their CV and passport/visa documents during regular business hours (Monday-Friday, 7am–4pm). Evening and weekend check-in is NOT available.

The Department of Energy (DOE) requires all foreign nationals (non-U.S. citizens) looking to conduct work on-site at SLAC to provide their curriculum vitae (email and bring CV to SLAC). Please ensure that all academic and employment activities since college (Associate/Bachelor or equivalent) are listed chronologically with no gaps in time, including month/year and relevant area(s) of science or technology. Please do NOT include protected personal identification information such as birthdate, government ID or passport/visa numbers. CVs will be uploaded to the DOE's Foreign Access Central Tracking System (FACTS). By submitting this information, you consent to SLAC providing this information to the DOE.

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.
