Abstract
Abstract
Increasing the Main Injector beam power above ∼ 1.2 MW
requires replacement of the 8 GeV Booster by a higher intensity
alternative. In this paper, we consider an 8 GeV linac Booster
replacement that produces 8 GeV H- beam for injection into the
Recycler Ring or Main Injector. This upgrade will maximize the beam
available for neutrino production for the long baseline DUNE
experiment to greater than 2.5 MW and enable a next generation of
intensity frontier experiments. The 8 GeV linac takes ∼ 1 GeV
beam from the PIP-II Linac and accelerates it to ∼ 2 GeV in a
650 MHz superconducting RF linac, followed by a ∼ 2 to 8 GeV
pulsed linac using 1300 MHz cryomodules. The linac components
incorporate recent improvements in superconducting RF
technology. The linac configuration and beam dynamics requirements
are presented. Injection options are discussed, including use of an
8 GeV Accumulator Ring. Foil-based injection is the present
standard but R&D toward implementing laser-assisted injection could
enable a significant improvement. Research needed to implement the
Booster replacement is described.
