New requirements for access to SLAC

Due to the COVID pandemic there are NEW requirements for access to SLAC. These requirements are based on adherence to SLAC’s COVID-19 mitigation protocols and established levels of specific work criteria detailed on the Job Safety Analysis (JSA) form for all individuals coming on site.

Only for Users Approved for SLAC Onsite Access: Proceed to the VUE Center (1st floor Science and User Support Building 053) to check in, get badged, and update your proximity access. Check-in is from 7:00 a.m. to 5:00 p.m., Monday - Friday.  See below links for help with settling in the area and getting started with your experiment at LCLS.

Please clean up your work area before you leave. Log in to the User Portal to complete an end of run survey after each scheduled experiment. Your feedback will be used to address issues and continually improve user resources and support. LCLS also needs your help to compile metrics that demonstrate scientific accomplishments and productivity. Please submit LCLS related publications and inform us of awards, patents, etc.
