All Other Guests to SLAC

Guests and visitors working at SLAC will need to have proper identification documentation with them when they arrive at the laboratory to be granted site access and to be allowed to work. Please make sure that you bring the appropriate documents with you to avoid any delays during check-in. Your SLAC sponsor/point of contact (POC) will coordinate with you any pre-arrival actions that may be necessary for your visit. See the Visitors and Users pages for more information.

If you do not have a SLAC badge or your badge is expired, and you are arriving at SLAC outside of business hours, please enter via the main gate on Sand Hill Road. A temporary badge will be issued to users and other approved visitors who have completed the necessary pre-arrival steps and are on the site access list. You will then need to check in at the VUE Center on the next business day to obtain your SLAC badge.
If you are a construction subcontractor, your SLAC POC will need to complete a Subcontractor/Vendor After Hours Site Entry form for all work to be performed at SLAC after business hours and weekends, and ensure that you have a valid badge and training before you can enter the site outside SLAC work hours (SLAC work hours are Monday-Friday from 06:00am to 06:00pm). The SLAC field construction manager must be on site when you are here after hours and on weekends.
If you have any questions about the arrival process, please contact your SLAC POC or the VUE Center.
