Planning Ahead Getting Beam Time


Onsite Logistics and Additional Resources

We take very seriously the challenges of safety and security here. Please review the access guidelines which are intended to call your attention to information related to visits to SLAC. The user office is here to help!
  • Beginning on February 1, 2019, 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.

  • New user registration requests and beam time/support requests listing proposal team members who plan to be on-site must be submitted at least 14 days before any planned visits.

  • Anticipate that user check-in at the SLAC VUE Center/Badging Office can take up to 4 hours.

  • Foreign nationals must arrive at the VUE Center for check-in with their CV and passport/visa documents during regular buisness hours (Monday-Friday, 7 am- 4 pm). Evening and weekend check-in is no longer available.

  • Users who have already checked in since September 2018 and have their valid SLAC ID badge with them do not need to check-in again with the SLAC VUE Center (unless returning after September 2019).
