KM3NeT is a research infrastructure located in the Mediterranean Sea, that will consist of two deep-sea Cherenkov neutrino detectors. With one detector (ARCA), the KM3NeT Collaboration aims at identifying and studying TeV–PeV astrophysical neutrino sources. With the other detector (ORCA), the neutrino mass ordering will be determined by studying GeV-scale atmospheric neutrino oscillations. The first KM3NeT detection units were deployed at the Italian and French sites between 2015 and 2017. In this paper, a description of the detector is presented, together with a summary of the procedures used to calibrate the detector in-situ. Finally, the measurement of the atmospheric muon flux between 2232–3386 m seawater depth is obtained.

ORCA (Oscillation Research with Cosmics in the Abyss) is the low-energy branch of KM3NeT, the next-generation research infrastructure hosting underwater Cherenkov detectors in the Mediterranean Sea. ORCA's primary goal is the determination of the neutrino mass hierarchy by measuring the matter-induced modifications on the oscillation probabilities of few-GeV atmospheric neutrinos. The ORCA detector design foresees a dense configuration of KM3NeT neutrino detection technology, optimised for measuring the interactions of neutrinos in the energy range of 3-20 GeV. To be deployed at the French KM3NeT site, ORCA's multi-PMT optical modules will exploit the excellent optical properties of deep-sea water to accurately reconstruct both shower-like (mostly electron neutrino) and track-like (mostly muon neutrino) events in order to collect a high-statistics sample of few-GeV neutrino events.This contribution reviews the methods and technology of the ORCA detector, and discusses the prospects for measuring the neutrino mass hierarchy as well as the potential to improve the measurement precision on other oscillation parameters.

“…The expected detector performance of Super-ORCA has been estimated based on full event reconstruction applied to a simplified detector response simulation. The neutrino interaction (GENIE 2.10.2), particle propagation as well as Cherenkov photon generation and tracking in seawater is fully simulated using a similar simulation framework as described in [83]. An up-to-date model of optical properties of the deep-sea water and optical background from 40 K decays is taken into account.…”

“…With the increased instrumentation density compared to ORCA, the energy threshold for neutrino detection is reduced to ∼ 0.5 GeV, and the ν μ /ν e separation via the fuzziness of the Cherenkov cones allows for a selection of 95%-pure samples of muon-like (dominated by ν μ CC) and electron-like events (dominated by ν e CC). The neutrino energy resolution is ≈ 20% at E ν > 1 GeV and is dominated by fluctuations in the number of emitted photons in the hadronic shower [83].…”

Letter of interest for a neutrino beam from Protvino to KM3NeT/ORCA

The Protvino accelerator facility located in the Moscow region, Russia, is in a good position to offer a rich experimental research program in the field of neutrino physics. Of particular interest is the possibility to direct a neutrino beam from Protvino towards the KM3NeT/ORCA detector, which is currently under construction in the Mediterranean Sea 40 km offshore Toulon, France. This proposal is known as P2O. Thanks to its baseline of 2595 km, this experiment would yield an unparalleled sensitivity to matter effects in the Earth, allowing for the determination of the neutrino mass ordering with a high level of certainty after only a few years of running at a modest beam intensity of $$\approx ~90~\hbox {kW}$$≈90kW. With a prolonged exposure ($$\approx 1500\hbox { kW}\,\,\hbox {year}$$≈1500kWyear), a $$2\sigma $$2σ sensitivity to the leptonic CP-violating Dirac phase can be achieved. A second stage of the experiment, comprising a further intensity upgrade of the accelerator complex and a densified version of the ORCA detector (Super-ORCA), would allow for up to a $$6\sigma $$6σ sensitivity to CP violation and a $$10^\circ {-}17^\circ $$10∘-17∘ resolution on the CP phase after 10 years of running with a 450 kW beam, competitive with other planned experiments. The initial composition and energy spectrum of the neutrino beam would need to be monitored by a near detector, to be constructed several hundred meters downstream from the proton beam target. The same neutrino beam and near detector set-up would also allow for neutrino-nucleus cross section measurements to be performed. A short-baseline sterile neutrino search experiment would also be possible.
