The Fermilab Booster is a synchrotron accelerator with a circumference of 474 meters. Beam is injected into the Booster from the 400 MeV transport line which carries the 400 MeV beam output from the Linac accelerator. The Booster accelerates a proton beam from 400 MeV to 8 GeV in less than 67 milliseconds for the Main Injector accelerator. Booster also provides beam for the MiniBooNE experiment and the NuMI facility and MINOS experiment.
