Jefferson Lab Site Tour
Test Lab - A Completed Cryounit
A thermos bottle is used to keep hot things hot or cold things cold. Cryomodules are just large thermos bottles used to keep liquid Helium, and the cavities that it surrounds, cold. This is one quarter of a full cryomodule. A full cryomodule is 32 feet long and weighs 6 tons. The cryomodules are eventually installed in the straight sections of 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.
