Fermilab Linac

The Fermilab Linac is a H- (negative hydrogen ion), 400MeV particle accelerator.

It includes a

35KeV H- ion source,
750KeV RIL (RFQ Injection Line including a Low & Medium Energy Beam Transport),
116MeV Drift-Tube (Alverez) Linac operating at 201.25MHz
401MeV Side-Coupled Cavity Linac operating at 805MHz.
Many details can be obtained from the picture displays listed in the sidebar to the left.

The Fermilab Linac provides beam for Booster operation at frequencies from 0.1 to 8 Hz.

Linac is also capable of providing 66MeV beam to the Fermilab Neutron Therapy Facility (NTF).

Linac beamcurrent 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.
