Title: Superbeams and neutrino factories — Two paths to intense accelerator-based neutrino beams

Abstract

High-energy and high-beam power accelerators are extensively used for the neutrino physics research. At present, the leading operational facilities are the J-PARC facility in Japan, which recently approached 0.5 MW of the 30 GeV proton beam power, and the Fermilab Main Injector complex that delivers over 0.75 MW of 120 GeV protons on the neutrino target. Besides such type of neutrino superbeams, the concept of neutrino factories offers great promise for particle physics research. In this brief review we present the status and planned upgrades of the J-PARC and Fermilab accelerators and leading proposals for the next generation accelerator-based facilities of both types, their challenges and required and ongoing accelerator R&D programs aimed to address corresponding performance and cost risks.

Fig. 1 Fig. 1: J-PARC neutrino beamline. 30 GeV protons out of the Main Ring synchrotron are directed into 90 cm long graphite target composed of graphite rods and produce secondary particles. Among those, π+ mesons converge in the forward direction under the focusing effect of magnetic horns, which powered by amore » few hundred kA current pulses synchronized with each beam shot. On a flight in a 100-m-long tunnel the pions decay into µ+νµ pairs. The muon neutrino (and a small fraction of muons) leave the facility, whereas all the other particles such as the remaining protons and undecayed π-mesons are absorbed by a beam dump composed of large graphite blocks. The profile of the muons that penetrate the beam dump is used as an indirect monitor of the νµ beam direction. Neutrino detectors located 280 m downstream of the target can measure the profile, purity, and energy distribution of the muon neutrinos. The neutrinos further travel 295 km through the Earth toward large Super-Kamiokande water Cherenkov detector (adapted from7).« less
