Extras!

Measuring over 170 feet across, experimental Hall A is the largest of the three end stations. The beam comes in from the accelerator tunnel and strikes a target mounted on the black pedestal in the center of the room. Detectors on twin arms can be moved around the room to measure where the particles fly.

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.
