Although the accelerator is not open very often, Public Affairs does offer tours of the Test Lab, where accelerator components are designed, tested and built.


Tours at Jefferson Lab

Jefferson Lab conducts research 24 hours a day, seven days a week. Tours of the accelerator, experimental halls and Free-Electron Laser (FEL) are based upon availability of those areas. When the accelerator is shut down for maintenance, tours may be scheduled if they do not interfere with planned work.

Tours of the SRF Test Lab, the Machine Control Center, and windshield tours of the accelerator site are possible throughout the year.

All visitors taking a tour are required to carry photo ID, be 18 years or older, wear low-heeled, closed-toe shoes, long pants, and provide proof of citizenship.

International visitors to Jefferson Lab must carry their passports or visas with them.

Open House is the only time when visitors under 18 can tour the lab. Jefferson Lab typically offers an Open House for the general public every other year. During Open House, no registration of visitors is required. The next Open House is scheduled for 2016.

Please allow at least two weeks notification for a tour of Jefferson Lab. Minimum size for a scheduled tour is 5 people.
