Young-Kee Kim: Future Neutrino Projects in the US

March 14, 2013

There are three frontiers: the energy, the intensity, and the cosmic frontier. At the intensity frontier, the US has a broad spectrum of neutrino physics programs. Accelerator based experiments using fermilab facilities are the focus of this talk.

One goal is to measure and characterize the pattern of neutrino masses and mixings: MINOS, MINOS+, NOVA, and LBNE. Another goal is to discover if the situation is more complex than a scenario with three neutrinos with SM interactions: to the previously listed experiments MiniBooNE, MicroBooNE and NuStorm come to help here. Then there are measurements of neutrino cross sections that make the above studies possible: Minerva will be useful along with the other experiments here.

Nova and MicroBoone use the same beamline of MINOS but have a different baseline (810 vs 735 km) and work off-axis. Nova has a 14kton surface liquid scintillator detector. Then there is LBNE, which at 1300 km has a far detector with >10kton extendable to 35 kton.

MicroBooNE is a 100 ton liquid argon TPC. The project is progressing very well. MINOS+ and MINERVA are at the same location. NOvA is in construction, so far 9 of the 28 blocks are already in place. Since they ended up doing things cheaper and faster, they received a National Recognition award. At the far detector NOVA has alread seen cosmic muons last months, running with 3kton is expected in June.

LBNE has a extraordinary physics reach. In phase 1 the goal is to build the beamline and a near detector and a >10kton detector underground. The DOE funded %850M, so with 20% in-kind contributions from foreign countries they can get everything done. A stronger neutrino flux is expected from ProjectX (up to 2.3 MW). At Sanford the underground research facility is 1.5 km underground. SURF wants you to visit the site, you will get a VIP tour !

Accelerator upgrades are ongoing at Fermilab. The main inkjector will double the beam power by stacking beam in the recycler and decreasing MI cycle time. The repetition rate in the proton source will also be doubled. At the Muon Campus the antiproton source will be converted to meet the needs of the new setup. Young-Kee showed a graph of booster flux in a ten-year timeline from 2010 to 2020 to clarify the various stages of operation and the experiments that will benefit from it. Then in 2020 Project X will have a >6MW total power at 1,3,8, 60-120 GeV. With ProjectX the US will see a broad program of neutrino experiments, rare processes searches, and more.
