This 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. In this white paper, we propose an 8 GeV Linac for that purpose. The Linac consists of an extension of the PIP-II Linac to ~2 GeV using PIP-II 650 MHz SRF cryomodules, followed by a 2 -->8.0 GeV ","authors_text":"A. Saini, D. Johnson, D. Neuffer, E. Pozdeyev, H.
