• Increasing the Main Injector beam power above ∼ 1.2 MWrequires replacement of the 8 GeV Booster by a higher intensityalternative. In this paper, we consider an 8 GeV linac Boosterreplacement that produces 8 GeV H- beam for injection into theRecycler Ring or Main Injector. This upgrade will maximize the beamavailable for neutrino production for the long baseline DUNEexperiment to greater than 2.5 MW and enable a next generation ofintensity frontier experiments. The 8 GeV linac takes ∼ 1 GeVbeam from the PIP-II Linac and accelerates it to ∼ 2 GeV in a650 MHz superconducting RF linac, followed by a ∼ 2 to 8 GeVpulsed linac using 1300 MHz cryomodules. The linac componentsincorporate recent improvements in superconducting RFtechnology. The linac configuration and beam dynamics requirementsare presented. Injection options are discussed, including use of an8 GeV Accumulator Ring. Foil-based injection is the presentstandard but R&D toward implementing laser-assisted injection couldenable a significant improvement. Research needed to implement theBooster replacement is described.
