Helium Storage Tanks

Two large Cold Boxes dominate this room inside the Central Helium Liquefier. Heat exchangers, cold compressors and other equipment needed to chill Helium down to a temperature of -456F are insulated from room temperature within these containers. This equipment requires a huge amount of electricity to operate. It costs about a million dollars a year to pay the power bill.

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.
