The Fermilab Linac is designed to accelerate negative hydrogen ions, which consist of a hydrogen with an additional electron, to 400 MeV. It provides beam for Booster operation at frequencies up to 15 Hz. It is also capable of providing 66 MeV beam to the Fermilab Neutron Irradiation Facility (NIF).
The Fermilab Linac contains the following parts:
- A 35 KeV H- ion source;
- A 750 KeV Radio Frequency Quadrupole RFQ injector line with a Low & Medium Energy Beam Transport (LEBT/MEBT);
- A 116 MeV Drift-Tube Alverez Linac operating at 201.25 MHz; and
- A 400 MeV Side-Coupled Cavity Linac operating at 805 MHz.
Many details can be obtained from the picture displays listed in the sidebar to the left.
Linac Performance Plots
Linac beam current over the last 24 hours (updated every 10 minutes, beginning at :02).
Linac beam lasts between 15 and 50 &mu sec, and repeats at 15 Hz, for a duty factor between 0.0225% and 0.0750%. Zero current usually means that we are not being asked to produce beam for the rest of the facility.
