CEBAF Center - Cavity Display

What makes Jefferson Lab's electron beam go? Niobium cavities, like this one, kick the electrons in the beam as they pass through them. Every time an electron gets kicked, it gets a little more energy. Each cavity is about half a meter long and costs about $30,000. Most of the accelerator's 338 cavities can be found in the long, straight sections.

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.
