- Berkeley Lab Guest House – ALS users should follow the Guest House booking guidance found here.
Further onsite access and arrival information specific to users can be found here.
Contact your host at the Lab or the ALS User Services Office to arrange for clearance through the Lab’s front gate (Blackberry Gate). Bring a photo ID (for non–U.S. citizens this must be a valid passport).
You must be a Berkeley Lab employee or visiting researcher (participating guest) with an LDAP account to arrange for gate clearance for visitors. By 3:00 pm on the day before the visit, submit a Visitor Pass Request. Complete the online form with the name(s) of any visitors, their arrival time, and your name and contact information. If you miss the 3:00 pm deadline, call the Site Access Office (ext. 4551). After hours, call the security the guard on duty at the Blackberry Gate (ext. 5472).
Parking at Berkeley Lab and the ALS is by permit only. Signs in each parking lot designate the types of permit required for that area. Cars parked in no-parking areas or reserved spaces without appropriate permits may be cited or towed.
A one-day permit must be obtained at the Berkeley Lab Main Gate (Blackberry Gate). Longer-term parking permits are issued by the Berkeley Lab Site Access Office (Building 65A, by the bus stop after the main gate) to eligible ALS users after their registration is completed.
A few spaces close to the ALS are available to users with a special need and may be reserved on a first-come basis. Send an email to firstname.lastname@example.org, with details of date and times and a short justification for the request. Reservations are not required for parking outside of regular business hours.
If you have not completed the required safety training, you must be accompanied by an escort while on the experiment floor of Building 6. Escorts are directly responsible for your safety and must accompany you at all times while inside the ALS. If your work requires unescorted access, you must register with the User Services Office by creating an account on ALSHub. For additional information, contact the User Services Office.
