View Presentation Abstract
The Proton Improvement Plan II (PIP-II) project is an essential upgrade to Fermilab’s particle accelerator complex. PIP-II will enable the world’s most intense neutrino beam for the international Long Baseline Neutrino Facility (LBNF)/Deep Underground Neutrino Experiment (DUNE), and a broad particle physics program for many decades to come. IP-II will deliver 1.2 MW of proton beam power from the Main Injector over the energy range 60 – 120 GeV, upgradeable to multi-MW capability, and will provide a flexible platform for extension to Continuous Wave (CW) beam operation, multiple users, and high reliability.
The central element of PIP-II is an 800 MeV linac, which comprises a room temperature front end, up to 2.1 MeV, followed by a SRF accelerator. In order to retire a significant number of technical risks, the front end has been constructed and operated with (pulsed & CW) beam in the PIP-II Injector Test facility. The SRF accelerator consists of five different types of cavities/cryomodules, each optimized for a certain proton velocity, including Half Wave Resonators, Single Spoke and elliptical resonators operating at state of the art parameters.
PIP-II is the first U.S. accelerator project that will be constructed with significant contributions from international partners, including India, Italy, France and the United Kingdom. DOE’s Argonne and Lawrence Berkeley national laboratories are also contributing key technologies. The project received CD-1 approval in July 2018. Start of site construction is scheduled for March 2019. The project will be completed in 2027.
The American Physical Society (APS) is a non-profit membership organization working to advance the knowledge of physics.
