This large, pink building is called the Test Lab. Technicians inside the Test Lab test Jefferson Lab's niobium acceleration cavities, cryogenic containers and electromagnets before they are installed in the accelerator tunnel.

This tour reflects Jefferson Lab as it was in the late 1990s and early 2000s. In particular, this predates the 12 GeV upgrade and the addition of Hall D. For a modern look at the Lab, please see the Jeffeson Lab Virtual Tour.
