Neutrino experiments are scientific studies investigating the properties of neutrinos, which are subatomic particles that are very difficult to detect due to their weak interactions with matter. Neutrino experiments are essential for understanding the fundamental properties of matter and the universe's behaviour at the subatomic level.
The first of the two prototypes, the single-phase ProtoDUNE (CERN experiment NP04 [23]), recorded its first particle tracks in September 2018. [24] CERN's participation in DUNE marked a new direction in CERN's neutrino's research [25] and the experiments are referred to as part of the Neutrino Platform in the laboratory's research programme. [26]
The director of the experiment, Art McDonald, was co-awarded the Nobel Prize in Physics in 2015 for the experiment's contribution to the discovery of neutrino oscillation. [1] The underground laboratory has been enlarged into a permanent facility and now operates multiple experiments as SNOLAB.
Most neutrino experiments must address the flux of cosmic rays that bombard the Earth's surface. The higher-energy (>50 MeV or so) neutrino experiments often cover or surround the primary detector with a "veto" detector which reveals when a cosmic ray passes into the primary detector, allowing the corresponding activity in the primary detector ...
The Homestake experiment was followed by other experiments with the same purpose, such as Kamiokande in Japan, SAGE in the former Soviet Union, GALLEX in Italy, Super Kamiokande, also in Japan, and SNO (Sudbury Neutrino Observatory) in Ontario, Canada. SNO was the first detector able to detect neutrino oscillation, solving the solar neutrino ...
In the KATRIN experiment the spectrum around this end-point is measured with high precision to obtain the neutrino mass. Timeline of neutrino mass measurements by different experiments. [5] The beta decay of tritium is one of the least energetic beta decays. The electron and the neutrino which are emitted share only 18.6 keV of
There is an affiliated project in the Aberdeen Tunnel Underground Laboratory in Hong Kong. The Aberdeen lab measures the neutrons produced by cosmic muons which may affect the Daya Bay Reactor Neutrino Experiment. The experiment consists of eight antineutrino detectors, clustered in three locations within 1.9 km (1.2 mi) of six nuclear reactors.
The Cowan–Reines neutrino experiment was conducted by physicists Clyde Cowan and Frederick Reines in 1956. The experiment confirmed the existence of neutrinos . Neutrinos, subatomic particles with no electric charge and very small mass, had been conjectured to be an essential particle in beta decay processes in the 1930s.
