  The Fermilab Proton Source machines, constituted by Pre-Injector,
conventional Linac and Booster synchrotron, at Fermi National Accelerator
Laboratory (Fermilab) had have a long history of successful beam operations.
Built in late '60s, the Fermilab Proton Source began operations early in the
'70s and since then it has successful provided protons to support the
laboratory physics experiments. During the past decade, Booster performance
reached unprecedented proton flux delivery of the order of 1.0-1.1E17 protons
per hour, corresponding to 40 kW of beam power while maintained an allowed
upper limit of 525 W of beam loss in the tunnel. In order to achieve this
historical performance, major hardware upgrades were made in the machine
combined with improvements in beam orbit control and operational awareness.
Once again, the Proton Source has been charged to double their beam throughput,
while maintaining the present residual activation levels, to meet the
laboratory Intensity Frontier program goals until new machines are built and
operational to replace them. In this paper we will discuss the plans involved
in reaching even higher beam throughput in Booster.
