SLAC has installed proximity card readers at the entrances from Sand Hill Road and Alpine Road as well as at Security Gates 17 and 30. If you do not have an ID badge with proximity access, provide photo ID to SLAC Security at the Main Gate. For arrival during office hours which are 7 am-12 noon and 1-4 pm (except weekends and holidays), turn right at the main SLAC entrance and visit the Security Office first. After confirming that you are affiliated with a scheduled experiment and your training is complete, Security will provide a temporary proximity card (if arriving after hours, Security guards at the Sand Hill Road Main Gate can provide a temporary proximity card). Check in with URA in Building 120 before 4 pm to obtain a SLAC User Photo ID badge with proximity access for 30-90 days. Contact URA to reactivate your proximity access for future visits. If you do not plan to return to  SLAC, please drop off your ID badge with URA staff before you leave.

Services provided by SLAC Security at the Sand Hill Road Main Gate include:

  • After Hours and Holidays: Proximity card required for access. Alternatively, officers will log in every car or individual entering SLAC property from sunset to 6 am and on all shifts during weekends and holidays.
  • Directions and Maps: Directions and maps are available from Security or the web.
  • Emergency Assistance: In the event of an emergency or life threatening situation, call 911 or extension 5555 from any SLAC telephone (650-926-5555). Also notify your supervisor, the Duty Operator or SSRL Safety Officer.
  • Telephone Services: The Main Gate Security Officers provide general telephone assistance with call transferring, offsite calling, and overseas calls. For specific SLAC telephone information, refer to the SLAC Telephone User's Guide.
  • Visitors: Security Officers will provide visitors with SLAC personnel contact/directory (SLAC phone directory) assistance, and directions and maps. If SLAC contact cannot be reached, visitors will be asked to wait in the Visitor's parking lot until contact is made. If you are expecting a visitor and want to make their his/her experience as simple as possible, please contact the Main Gate security guards in advance to make prior arrangements for the visit.
