“…The matter effect on neutrinos plays an important role for studying the mass hierarchy. Apart from ICAL at INO, future proposed detectors elsewhere aim to observe the earth matter effects on atmospheric neutrinos including the megaton water Cherenkov detectors such as Hyper-Kamiokande (HK) [18], large liquid argon detectors [19,20] and a gigaton-class ice detector such as the Precision IceCube Next Generation Upgrade (PINGU) [21,22]. The mass hierarchy and CP violation problem will also be addressed by accelerator based neutrino experiments such as NOvA [23], LBNE [24], and T2K [9].…”

Abstract-The iron calorimeter (ICAL) detector at the Indiabased Neutrino Observatory (INO) will be used to measure neutrino mass hierarchy. The magnet in the ICAL detector will be used to distinguish the μ and μ + events induced by µ and anti-µ respectively. Due to the importance of the magnet in ICAL, an electromagnetic simulation has been carried out to study the B-field distribution in iron using various designs. The simulation shows better uniformity in the portion of the iron layer between the coils, which is bounded by regions which have lesser field strength as we move to the periphery of the iron layer. The ICAL magnet was configured to have a tiling structure that gave the minimum reluctance path while keeping a reasonably uniform field pattern. This translates into less Ampere-turns needed for generation of the required magnetic field. At low Ampere-turns, a larger fractional area with |B| ≥ 1 Tesla (T) can be obtained by using a soft magnetic material. A study of the effect of the magnetic field on muon trajectories has been carried out using GEANT4. For muons up to 20 GeV, the energy resolution improves as the magnetic field increases from 1.1 T to 1.8 T. The charge identification efficiency for muons was found to be more than 90% except for large zenith angles.

“…Earlier studies of this were undertaken in [40][41][42] and, more recently, in [43][44][45]. We also note that the muon survival rate is a major constituent of the signal in the existing SK [2,3] detector, the planned megaton water Cerenkov detectors like Underground Nucleon decay and Neutrino Observatory (UNO) or Hyper-Kamiokande [27,34,46], and several detectors considered for future long baseline facilities [47], for which the discussion below may be of relevance.…”

Earth matter effects at very long baselines and the neutrino mass hierarchy

et al. 2006

We study matter effects which arise in the muon neutrino oscillation and survival probabilities relevant to atmospheric neutrino and very long baseline ( > 4000 Km) beam experiments. The interrelations between the three probabilities P e , P , and P are examined. It is shown that large and observable sensitivity to the neutrino mass hierarchy can be present in P and P . We emphasize that at baselines >7000 Km, matter effects in P are important under certain conditions and can be large. The muon survival rates in experiments with very long baselines thus depend on matter effects in both P and P e . We also indicate where these effects provide sensitivity to 13 and identify ranges of energies and baselines where this sensitivity is maximum. The effect of parameter degeneracies in the three probabilities at these baselines and energies is studied in detail and large parts of the parameter space are identified which are free from these degeneracies. In the second part of the paper, we focus on using the matter effects studied in the first part as a means of determining the mass hierarchy via atmospheric neutrinos. Realistic event rate calculations are performed for a charge discriminating 100 kT iron calorimeter which demonstrate the possibility of realizing this very important goal in neutrino physics. It is shown that for atmospheric neutrinos, a careful selection of energy and baseline ranges is necessary in order to obtain a statistically significant signal, and that the effects are largest in bins where matter effects in both P e and P combine constructively. Under these conditions, up to a 4 signal for matter effects is possible (for 31 > 0) within a time scale appreciably shorter than the one anticipated for neutrino factories.

“…This sign can be extracted via the detection of earth matter effects in atmospheric and accelerator-based neutrino beams. Proposed detectors aiming to observe earth matter effects in atmospheric neutrinos include the Iron CALorimeter (ICAL) at the India-based Neutrino Observatory (INO) [15], megaton water Cerenkov detectors such as the Hyper-Kamiokande (HK) [16], large liquid argon detectors [17,18] and a gigatonclass ice detector such as the Precision IceCube Next Generation Upgrade (PINGU) [19,20]. The accelerator beam neutrino experiment NOνA [21], which will start operating soon, will also be sensitive to the mass hierarchy.…”

The India-based Neutrino Observatory (INO) will host a 50 kt magnetized iron calorimeter (ICAL@INO) for the study of atmospheric neutrinos. Using the detector resolutions and efficiencies obtained by the INO collaboration from a full-detector GEANT4-based simulation, we determine the reach of this experiment for the measurement of the atmospheric neutrino mixing parameters (sin 2 θ 23 and |∆m 2 32 |). We also explore the sensitivity of this experiment to the octant of θ 23 , and its deviation from maximal mixing.
