On Thursday the laboratory presented to our staff and users its plan for providing megawatt proton beams to the neutrino program at Fermilab. We will present this plan formally to the P5 advisory panel in the meeting at Brookhaven National Laboratory on Monday.
Over the last two months, the accelerator sector has worked diligently to develop and document a cost-effective concept, named Proton Improvement Plan-II, or PIP-II, that will make Fermilab the best in the world for accelerator-based neutrino experiments. At the same time, PIP-II will provide a platform for longer-term development of the accelerator complex to allow us to retain a world-leading particle physics program for many decades.
The central element of PIP-II is the construction of an 800-MeV superconducting linac injecting into the existing Booster. The higher injection energy will allow us to deliver 50 percent more beam intensity from the Booster and, when paired with modest improvements in the Recycler and Main Injector, will allow us to break the 1-MW barrier in beam power delivered to the Long-Baseline Neutrino Experiment. The plan is to have this capability in place at the time of initiation of LBNE operations.
The PIP-II concept is a descendant of the Project X reference design, with changes that significantly reduce the cost by aligning its capabilities more closely with the LBNE mission. The concept capitalizes directly on expertise in superconducting radio-frequency technologies developed at Fermilab over the last decade. It also significantly reuses existing Tevatron infrastructure, most notably the Central Helium Liquefier. By replacing our aging linac, PIP-II will provide a reliable source of protons at Fermilab for decades to come.
PIP-II is expected to be very attractive to international partners, including our Indian collaborators as well as several institutions in Europe and Asia.
We are all excited about the prospects for PIP-II and look forward to moving ahead following a positive recommendation from P5.
