P-ONE
The Pacific Ocean Neutrino Experiment, or P-ONE, is a proposed neutrino observatory using an area of the north-eastern Pacific Ocean off the coast of British Columbia, Canada, to entrap neutrinos for study and experimentation. The proposal involves building a multi-cubic-kilometer neutrino telescope at Ocean Networks Canada’s Cascadia Basin site in the North East Pacific Time-series Underwater Networked Experiment (NEPTUNE) coastal network. Although a considerable number of neutrinos are produced in the universe, they are emitted at a considerably low flux, and therefore require a large detection array for their capture.

Neutrino Detector
A neutrino detector is a physics apparatus which is designed to study neutrinos. Because neutrinos only Weak interaction, weakly interact with other particles of matter, neutrino detectors must be very large to detect a significant number of neutrinos. Neutrino detectors are often built underground, to isolate the detector from cosmic rays and other background radiation. The field of neutrino astronomy is still very much in its infancy – the only confirmed extraterrestrial sources are the Sun and the SN 1987A, supernova 1987A in the nearby Large Magellanic Cloud. Another likely source (three standard deviations) is the blazar TXS 0506+056 about 3.7 billion light years away. Neutrino observatories will "give astronomers fresh eyes with which to study the universe". Various detection methods have been used. Super Kamiokande is a large volume of water surrounded by phototubes that watch for the Cherenkov radiation emitted when an incoming neutrino creates an electron or muon ...

Hyper-Kamiokande
Hyper-Kamiokande is a neutrino observatory being constructed on the site of the Kamioka Observatory, near Kamioka, Japan. The project started in 2010 as a successor to Super-Kamiokande. It was ranked as among the 28 top priority projects of the Japanese government. Thirteen countries from three continents are involved in this program. Construction was given final approval on 13 December 2019. Mass production of the photomultiplier tube detectors began in 2021. Construction of the access tunnel was completed on February 25, 2022. The beginning of data-taking is planned for 2027. Hyper-Kamiokande will have a tank with a billion litres of ultrapure water (UPW), 20 times larger than the tank for Super-Kamiokande. This increased capacity will be accompanied by a proportional increase in the number of sensors. The tank for Hyper-Kamiokande will be a double cylinder 2 × 250 meters long, always approximately 40 × 40 meters, and buried 650 meters deep to reduce interference from cosmic ra ...

INSPIRE-HEP
INSPIRE-HEP is an open access digital library for the field of high energy physics (HEP). It is the successor of the Stanford Physics Information Retrieval System (SPIRES) database, the main literature database for high energy physics since the 1970s. History SPIRES was (in addition to the CERN Document Server (CDS), arXiv and parts of Astrophysics Data System) one of the main Particle Information Resources. A survey conducted in 2007 found that SPIRES database users wanted the portal to provide more services than the, at that time, already 30-year-old system could provide. On the second annual Summit of Information Specialists in Particle Physics and Astrophysics in May 2008, the physics laboratories CERN, DESY, SLAC and Fermilab therefore announced that they would work together to create a new Scientific Information System for high energy physics called INSPIRE. It interacts with other HEP service providers like arXiv.org, Particle Data Group, NASA's Astrophysics Data System. and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super-Kamiokande
Super-Kamiokande (abbreviation of Super-Kamioka Neutrino Detection Experiment, also abbreviated to Super-K or SK; ja, スーパーカミオカンデ) is a neutrino observatory located under Mount Ikeno near the city of Hida, Gifu Prefecture, Japan. It is located underground in the Mozumi Mine in Hida's Kamioka area. The observatory was designed to detect high-energy neutrinos, to search for proton decay, study solar and atmospheric neutrinos, and keep watch for supernovae in the Milky Way Galaxy. It consists of a cylindrical stainless steel tank about in height and diameter holding 50,000 metric tons (55,000 US tons) of ultrapure water. Mounted on an inside superstructure are about 13,000 photomultiplier tubes that detect light from Cherenkov radiation. A neutrino interaction with the electrons or nuclei of water can produce an electron or positron that moves faster than the speed of light in water, which is slower than the speed of light in a vacuum. This creates a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MINOS
In Greek mythology, Minos (; grc-gre, Μίνως, ) was a King of Crete, son of Zeus and Europa. Every nine years, he made King Aegeus pick seven young boys and seven young girls to be sent to Daedalus's creation, the labyrinth, to be eaten by the Minotaur. After his death, Minos became a judge of the dead in the underworld. The Minoan civilization of Crete was named after him by the archaeologist Sir Arthur Evans. Etymology "Minos" is often interpreted as the Cretan word for "king", or, by a euhemerist interpretation, the name of a particular king that was subsequently used as a title. According to La Marle's reading of Linear A, which has been heavily criticised as arbitrary, we should read ''mwi-nu ro-ja'' (Minos the king) on a Linear A tablet. La Marle suggests that the name'' mwi-nu'' (Minos) is expected to mean 'ascetic' as Sanskrit ''muni'', and fits this explanation to the legend about Minos sometimes living in caves on Crete. The royal title ''ro-ja'' is read o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KM3NeT
The Cubic Kilometre Neutrino Telescope, or KM3NeT, is a future European research infrastructure that will be located at the bottom of the Mediterranean Sea. It will host the next-generation neutrino astronomy, neutrino telescope in the form of a water Cherenkov detector with an instrumented volume of several cubic kilometres distributed over three locations in the Mediterranean: KM3NeT-Fr (off Toulon, France), KM3NeT-It (off Portopalo di Capo Passero, Sicily, Italy) and KM3NeT-Gr (off Pylos, Peloponnese, Greece). The KM3NeT project continues work done under the ANTARES (telescope), ANTARES (telescope built off coast of France), Neutrino Mediterranean Observatory, NEMO (planned telescope off coast of Italy) and NESTOR Project, NESTOR (planned telescope off coast of Greece) neutrino telescope projects. KM3NeT will search for neutrinos from distant astrophysical sources like supernova remnants, gamma-ray bursts, supernovae or colliding stars and will be a powerful tool in the searc ...

IceCube Neutrino Observatory
The IceCube Neutrino Observatory (or simply IceCube) is a neutrino observatory constructed at the Amundsen–Scott South Pole Station in Antarctica. The project is a recognized CERN experiment (RE10). Its thousands of sensors are located under the Antarctic ice, distributed over a cubic kilometre. Similar to its predecessor, the Antarctic Muon And Neutrino Detector Array (AMANDA), IceCube consists of spherical optical sensors called Digital Optical Modules (DOMs), each with a photomultiplier tube (PMT) and a single-board data acquisition computer which sends digital data to the counting house on the surface above the array. IceCube was completed on 18 December 2010. DOMs are deployed on strings of 60 modules each at depths between 1,450 and 2,450 meters into holes melted in the ice using a hot water drill. IceCube is designed to look for point sources of neutrinos in the teraelectronvolt (TeV) range to explore the highest-energy astrophysical processes. In November 2013 it was ...

ANTARES (telescope)
ANTARES is the name of a neutrino detector residing 2.5 km under the Mediterranean Sea off the coast of Toulon, France. It is designed to be used as a directional neutrino telescope to locate and observe neutrino flux from cosmic origins in the direction of the Southern Hemisphere of the Earth, a complement to the South Pole neutrino detector IceCube that detects neutrinos from both hemispheres. The name comes from Astronomy with a Neutrino Telescope and Abyss environmental RESearch project; the acronym is also the name of the prominent star Antares. The experiment is a recognized CERN experiment (RE6). Other neutrino telescopes designed for use in the nearby area include the Greek NESTOR telescope and the Italian NEMO telescope, which are both in early design stages. The data taking of ANTARES was finished in February 2022, after 16 years of continuous operation. Design The array contains a set of twelve separate vertical strings of photomultiplier tubes. Each one has 7 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baikal Deep Underwater Neutrino Telescope
The Baikal Deep Underwater Neutrino Telescope (BDUNT) (russian: Байкальский подводный нейтринный телескоп) is a neutrino detector conducting research below the surface of Lake Baikal (Russia) since 2003. The first detector was started in 1990 and completed in 1998. It was upgraded in 2005 and again starting in 2015 to build the Baikal Gigaton Volume Detector (Baikal-GVD.) BDUNT has studied neutrinos coming through the Earth with results on atmospheric muon flux. BDUNT picks up many atmospheric neutrinos created by cosmic rays interacting with the atmosphere – as opposed to cosmic neutrinos which give clues to cosmic events and are therefore of greater interest to physicists. Detector history The start of the Baikal neutrino experiment dates back to 1 October 1980, when a laboratory of high-energy neutrino astrophysics was established at the Institute for Nuclear Research of the former Academy of Sciences of the USSR in Moscow. This laborato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
