• PIP-II is designed for >1 MW over 60 – 120 GeV and 1.2 MW at 120 GeV
• Provides platform for upgrade to >2 MW
• Linac beam power of 1.6 MW (CW), programmable bunch patterns
• Facility enables simultaneous, multi-user, high beam power operations
– Switch yard to provide beams to Muon Campus in multiuser mode with LBNF
– Upgrades to mu2e (in conjustion with LBNF/DUNE), truly requires PIP-II’s
CW capability.
• Linac tunnel includes space and infrastructure to reach 1 GeV
• Tunnel extension (by 120 m) compatible with energy 2–2.5 GeV
• Beam current can be increased by a factor of a few by upgrading amplifiers
