Proton Improvement Plan-II (PIP-II) is Fermilab's plan for providing powerful, high-intensity proton beams to the laboratory's experiments. The increased beam power will position Fermilab as the leading laboratory in the world for accelerator-based neutrino experiments. PIP-II will also provide a flexible platform for further enhancement of the Fermilab accelerator complex to extend this leadership to the full range of particle physics research based on intense beams in the decades to come.
The heart of PIP-II is a 800-MeV superconducting linear accelerator, which capitalizes on the lab's expertise in superconducting radio-frequency technologies. Along with modest improvements to Fermilab's existing Main Injector and Recycler accelerators, the superconducting linac, called SCL, will provide the megawatt proton beam that is needed for the Long-Baseline Neutrino Facility.
PIP-II is planned to deliver beam in the early part of the next decade.
