KM3NeT/ORCA is a water Cherenkov neutrino detector currently under construction in the Mediterranean Sea as part of the wider KM3NeT observatory, at a depth of 2450m offshore from Toulon, France. In its current configuration, it consists of 24 detection units out of a planned 115, each with 18 Digital Optical Modules comprising an 18” glass sphere containing 31 3” photomultipler tubes. In...
The IceCube neutrino observatory - comprised of a cubic kilometer of ice instrumented with over 5000 photo-multiplier tubes (PMTs) - has achieved world-leading precision measurements of atmospheric neutrino oscillation parameters in recent years. Such measurements inherently perform a simultaneous optical calibration of the detector, constraining relevant systematic uncertainties such as the...
The KM3NeT observatory hosts two undersea neutrino telescopes, ARCA and ORCA, located at two abyssal sites of the Mediterranean sea. The detectors consist of a 3D array of optical modules, each housing 31 3-inch photomultiplier tubes to detect Cherenkov light emitted by charged particles produced in neutrino interactions in water. Although still under construction, both detectors are already...
Building on the remarkable successes in neutrino astronomy in recent years, TRIDENT is a planned, large-scale neutrino telescope that seeks to advance the frontier of high-energy astrophysical neutrino detection. TRIDENT is to be deployed 3.5 km deep in the “Hai-ling Basin” of the South China Sea, expecting to span approximately 10 km³ of seawater with ~km-long strings equipped with optical...
Pre-supernova neutrinos are predominantly produced through thermal processes and nuclear weak interactions in massive stars during the final stages of stellar evolution, with increasing energy and luminosity. The detection of these neutrinos provides an early warning of core-collapse supernovae to neutrino, gravitational wave, and electromagnetic telescopes.
KamLAND, a 1-kiloton liquid...
Core-collapse Supernovae (SN) represent critical astronomical events where nearly an entire star's binding energy is emitted as neutrinos. RES-NOVA addresses a significant challenge in astroparticle physics by introducing a novel neutrino detection method using cryogenic detectors constructed from ultra-pure archaeological lead (Pb). The project's key innovation lies in leveraging Coherent...
The Pacific Ocean Neutrino Experiment (P-ONE) is a new large-volume neutrino telescope planned for installation in the Pacific Ocean off the West Coast of Canada. In the ocean, ever-changing conditions necessitate precise calibration systems to continuously monitor the detector. Primarily, ocean currents will sway the one-km-tall mooring lines over time, and detector positioning is crucial for...
Euclid is a mission of the European Space Agency (ESA), designed to investigate the content and evolution of the Universe. Launched in July 2023, the satellite will collect data for at least six years, covering one-third of the sky. Euclid holds the promise to provide crucial new constraints on relevant cosmological parameters, including the sum of the neutrino masses.
Accurate cosmological...
The KM3NeT Collaboration is deploying an advanced deep-sea neutrino detector in the Mediterranean Sea, aiming to explore neutrinos across a broad energy spectrum. This is achieved through two detectors, ARCA and ORCA, that share the same Cherenkov detection principle, but differ in their geometrical layout to address distinct physics goals. A central component of KM3NeT is its novel Digital...
T2K is a long-baseline experiment measuring neutrino and antineutrino oscillations by observing the disappearance of muon neutrinos, as well as the appearance of electron neutrinos, over a long 295km distance. The ND280 near detector at J-PARC plays a crucial role to minimise the systematic uncertainties related to the neutrino flux and neutrino-nucleus cross-sections as it measures the...
The Near Detector of the T2K experiment at J-PARC has recently been upgraded in order to reduce the present systematic uncertainties affecting the oscillation parameters measurements and to exploit the increased neutrino beam power of the J-PARC complex.
One of the major improvement to the T2K ND280 detector consisted in the the integration of two large-sized (~ 3m3 each) new horizontal...
The off-axis magnetic near detector of the T2K experiment has undergone a significant upgrade, including the construction and installation of two new Time Projection Chambers featuring innovative resistive Micromegas technology and a field cage composed of thin composite walls. This contribution provides a detailed description of the new components of the chambers, including the gas system,...
The Tokai-to-Kamioka (T2K) experiment is a long-baseline neutrino experiment. T2K obtained results that exclude the CP conservation with a 90% confidence level so far. Toward more precise measurements of the oscillation parameters, T2K experiment recently started operation of upgraded near detectors to further reduce major systematic errors on the neutrino-nucleus interaction. An upstream part...
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kton liquid scintillator detector housed in a laboratory approximately 650 meters underground. Its primary scientific goal is to determine the neutrino mass ordering by studying the oscillated anti-neutrino flux emitted from two nuclear power plants located 53 kilometers away. Given the extremely low expected signal rate, only 60...
The Deep Underground Neutrino Experiment, DUNE, is a next-generation, long-baseline, neutrino experiment and flagship project of the U.S. It is poised to perform some of the most precise measurements of the properties of neutrinos to elucidate their role in the outstanding matter-antimatter asymmetry. DUNE will make use of the most intense neutrino beam, produced at the Fermi National...
