Status of the Precision IceCube Next Generation Upgrade (PINGU)The IceCube Neutrino Observatory, completed in 2010 and located at the geographic South Pole, is the largest neutrino telescope in the world. IceCube includes the more densely instrumented DeepCore subarray, which increases IceCube's sensitivity at neutrino energies down to 10 GeV. DeepCore has recently demonstrated sensitivity to muon neutrino disappearance from atmospheric neutrino oscillation. A further extension is under consideration, the Precision IceCube Next Generation Upgrade (PINGU) which would lower the energy threshold and increase the sensitivity to low energy neutrino physics. In particular, PINGU would be sensitive to the effects of the neutrino mass hierarchy, which is one of the outstanding questions in particle physics. I will discuss the status of the planned PINGU array.Speaker: Prof. Dawn Williams (University of Alabama)

Recent status of J-PARC neutrino beamlineThe J-PARC neutrino beamline has had beam operation in the period May-June 2014 after a year long shutdown. Several beamline components were upgraded during the shutdown. The main upgrade was a replacement of all three magnetic horns. The new magnetic horns were upgraded to improve the acceptable beam power and to solve some known problems. The operation status of the neutrino beamline will be presented.Speaker: Dr Tetsuro Sekiguchi (KEK)

Accelerator design and modeling for the decay-at-rest neutrino experiments DAEδALUS and IsoDARThe proposed Decay-At-rest Experiment for δCP violation At the Laboratory for Underground Science (DAEδALUS) and the Isotope Decay-At-Rest experiment (IsoDAR), search for CP violation in the neutrino sector and sterile (non-interacting) neutrinos. Both are short baseline experiments that use proton driver beams. In the IsoDAR case, a 60 MeV proton beam will impinge on a high purity lithium/beryllium target to produce isotope decay-at-rest and in DAEδALUS, 800 MeV protons will hit a carbon target to produce pion/muon decay-at-rest. The drivers are cyclotrons, because they are comparatively cheap, compact and deliver the highest intensities in the considered energy range. In order to obtain the necessary high neutrino fluxes, the primary proton beam current needs to be even higher than current state-of-the-art machines at PSI have demonstrated. This has led to a substantial R&D effort on the accelerator side of DAEδALUS and IsoDAR. In this contribution, we will report on the latest driver designs and the challenges we are faced in creating, transporting, and accelerating high intensity beams.Speaker: Dr Daniel Winklehner (MIT)

Water-based Liquid ScintillatorThe newly developed, water-based liquid scintillator (WbLS) is an advanced scintillation liquid for future massive detectors with the unique capability of exploring physics below the Cherenkov threshold and has the ability of loading any (hydrophilic) metallic ions of interest for neutron tagging or other physics enhancements. The same water-based detector could also be used as a near detector for long baseline neutrino flux monitoring and an active water target for neutrino cross section measurement. In this presentation, the application of WbLS to a variety of physics topics will be discussed. *Research sponsored by the U.S. Department of Energy, Office of Nuclear Physics and Office of High Energy Physics, under contract with Brookhaven National Laboratory – Brookhaven Science AssociatesSpeaker: Dr Minfang Yeh (Brookhaven National Laboratory)

Sensitivity Studies for Near Detectors in a Tokai-to-Hyper-K ExperimentThe sensitivities for measuring CP violation and other neutrino oscillation parameters in a Tokai-to-Hyper-K long baseline experiment depend on systematic uncertainties in the neutrino flux and cross section models. These model uncertainties are constrained by data from near detectors. In this talk, I will present studies of the effect of near detector data on the CP violation sensitivity for different assumptions about the properties of the near detector, including its distance from the neutrino production point, the direction to the near detector, and the target material of the near detector.Speaker: Prof. Mark Hartz (Kavli IPMU (WPI), The University of Tokyo/TRIUMF)

65
TITUS selection with GdThe TITUS detector is an original multi-purpose new detector for the Hyper-K experiment, located 2 km from the J-PARC neutrino beam. TITUS consists of a gadolinium-doped water Cherenkov detector, partially enclosed by a muon range detector (MRD) The detector will be exposed to a neutrino flux similar to the Hyper-K far detector, minimising the uncertainty on the near-to-far extrapolation. The addition of Gadolinium allows neutron tagging which will provide discrimination between neutrino and anti-neutrino, and measurement of multi-nucleon interactions. Recent developments in the design of the TITUS water tank as well as software and physics analysis will be presented.Speaker: Dr David Hadley (University of Warwick)

A magnetized muon range detector for the 2km TITUS detectorThis talk will describe the advantages of surrounding the proposed 2km TITUS water Cherenkov with a magnetized iron range detector.

67
The nuPRISM Near DetectorIn order to reach the projected T2HK physics sensitivities, a better understanding of neutrino interaction uncertainties is required. The nuPRISM detector concept is a novel new technique to directly measure neutrino interaction final states for any oscillated spectra at Hyper-K. This removes neutrino interaction uncertainties from the accelerator-based oscillation measurements, and provides the first ever direct experimental constraint on the relationship between lepton kinematics (what experiments observe) and neutrino energy (what experiments wish to measure). In addition, nuPRISM provides a highly sensitive probe of the MiniBooNE sterile neutrino oscillation signal. Other measurements, such as unique cross section measurements, including the first ever measurements of neutral current cross sections as a function of neutrino energy, are also possible. The feasibility and current analysis status for a nuPRISM detector for Hyper-K will be presented.Speaker: Dr Michael Wilking (TRIUMF)
-
68
Short and long baseline sensitivities with nuPRISMThe nuPRISM detector concept provides a powerful tool for neutrino physics, using measurements at multiple off-axis angles to produce oscillated or mono-energetic neutrino beams. This talk describes the current long baseline sensitivity studies with nuPRISM, quantitatively demonstrating the benefits this technique brings to oscillation analyses. It will also discuss the short baseline sensitivities, comparing these to the MiniBooNE sterile searches.Speaker: Dr Mark Scott (TRIUMF)
