The Fermilab Linac is a H- (negative hydrogen ion), 400 MeV particle accelerator. It provides beam for Booster operation at frequencies from 0.1 to 8 Hz. It is also capable of providing 66MeV beam to the Fermilab Neutron Therapy Facility (NTF).
The Fermilab Linac contains the following parts:
- A 35 KeV H- ion source.
- A 750 KeV RIL (RFQ Injection Line, including a Low & Medium Energy Beam Transport)
- A 116 MeV Drift-Tube (Alverez) Linac operating at 201.25MHz
- A 401 MeV Side-Coupled Cavity Linac operating at 805MHz.
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.
