General Lab Information

Start your registration

Accessing Brookhaven Lab physically, remotely, or virtually? The first step for all guests, facility users, and visitors is to register through our Guest Information System.

Before You Arrive

Researchers must complete a series of registrations prior to arrival/access. Some visitors may also need to submit a User Agreement, reserve housing, open project accounts, and arrange to have materials shipped to the Lab.

When You Arrive

All guests, users, and visitors must check-in at the Guest, User, Visitor Center, Building 400E, prior to visiting their department and/or user facility. Check-in hours are 7:00 a.m. to 5:00 p.m., Monday through Friday, excluding holidays. Guests should make every attempt to arrive during these hours.

Preparing to Leave

There is a formal checkout procedure for all individuals working at Brookhaven. Chemicals, equipment, and other materials must be accounted for prior to your departure.



You are required to complete training associated with work that you will be performing, hazards that you may encounter, and the areas you will need to access. Work can only start once your training is complete.



For guests and users conducting research, an agreement must be in place before work begins. The type of agreement needed depends on the work being conducted, where the work is being done, and who is sponsoring the research.


ID Requirements

U.S. citizens age 16 and over must bring photo identification that has been issued by the federal government, or by your state government. Non-U.S. citizens have additional requirements.
