  The Fermi National Accelerator Laboratory (FNAL) Linac has been in operation
for 52 years. In approximately four years, it will be replaced by a new 800 MeV
superconducting machine, the PIP-II SRF Linac. In the current configuration,
the Linac delivers H- ions at 400 MeV and injects protons by charge exchange
into the Booster synchrotron. Despite its age, the Linac is the most stable
accelerator in the FNAL complex, reliably sending 22 mA in daily operations. We
will discuss the status of the operation, beam studies, and plans.
