Free Electron Laser - Linear Accelerator
The FEL's linear accelerator contains only one cryomodule and the electron beam is only accelerated through it once. In comparison, each one of Jefferson Lab's linear accelerators holds twenty cryomodules and the electron beam can pass through each one as many as five times. However, the cavities within the FEL's cryomodule are the best that Jefferson Lab's scientists have ever produced. The techniques learned in producing this cryomodule are being applied to Jefferson Lab's accelerator to upgrade its capabilities.
