“…The actual technical implementation requires, however, further study. Maybe even CP violation studies become possible if the detector can be further upgraded, a concept known as Megaton Ice Cherenkov Array, for which a fiducial masses of order 10 Mt may be reachable already below 1 GeV [60].…”

We discuss the neutrino mass hierarchy determination with atmospheric neutrinos in PINGU (Precision IceCube Next Generation Upgrade), based on a simulation with the GLoBES software including the full three flavor framework and parameter degeneracy, and we compare it to long-baseline experiment options. We demonstrate that the atmospheric mass hierarchy sensitivity depends on the achievable experiment properties and we identify the main targets for optimization, whereas the impact of a large number of tested systematical errors turns out to be small. Depending on the values of theta_23, delta, and the true hierarchy, a 90% CL to 3sigma discovery after three years of operation seems conceivable. We also emphasize the synergy with existing beam and reactor experiments, driven by NOvA, such as the complementary coverage of the parameter space. Finally, we point out that a low intensity neutrino beam with a relatively short decay pipe could be used to determine the mass hierarchy with a sensitivity comparable to the LBNE experiment irrespective of the directional resolution of the detector.Comment: 22 pages, 9 figures, 1 table.

“…Our reconstruction techniques can be easily applied to future liquid scintillator experiments, e.g. juno [30], hanohano [31], Deep-titand [32], and mica [33] once the detector configuration and timing resolutions become known. Neutrino experiments that employ alternative detection technologies, such as waterČerenkov detectors (e.g.…”

We show that current and imminent underground detectors are capable of precision astrometry of dark matter. First we show that galactic dark matter velocity distributions can be obtained from reconstructed tracks of dark matter scattering on multiple nuclei during transit; using the liquid scintillator neutrino detector sno+ as an example, we find that the dark matter velocity vector can be reconstructed event-by-event with such a small uncertainty, that the precision of dark matter astrometry will be limited mainly by statistics. We then determine the number of dark matter events required to determine the dispersion speed, escape speed, and velocity anisotropies of the local dark matter halo, and also find that with as few as O(10) events, dark matter signals may be discriminated from potential backgrounds arising as power-law distributions. Finally, we discuss the prospects of dark matter astrometry at other liquid scintillator detectors, dark matter experiments, and the recently proposed mathusla detector.

“…In simulations the WOM has been shown to detect more photons than the pDOM for all energies, types of events and detector geometries for IceCube-Gen2. Beyond IceCube-Gen2, it's high efficiency and low noise make this optical module the ideal candidate for the conceptualized MICA supernova detector [9]. The performance of the WOM can be improved even further by using new PMTs with a higher quantum efficiency or newly developed WLS.…”

The Wavelength-shifting Optical Module (WOM) is a novel photosensor concept developed in the context of the IceCube-Gen2 neutrino telescope, a next generation multi-km 3 neutrino telescope at the South Pole. It provides a large photosensitive area with low detector noise and improved UV sensitivity. This is achieved by combining a wavelength-shifter (WLS) coated tube with two small, low-noise PMTs. Incident UV photons are absorbed by the WLS and re-emitted isotropically. A large fraction of the light is captured in the tube by total internal reflection and guided to the small PMTs. Through its cylindrical geometry, which is well matched to the drill holes, this concept results not only in an overall improved detection efficiency, but at the same time saves production and drilling cost. In this contribution we discuss the performance characteristics of the WOM and present the current status of the prototype development.
