What is meant by neutrino oscillations? Neutrino oscillation is a quantum mechanical phenomenon in which a neutrino created with a specific lepton family number (“lepton flavor”: electron, muon, or tau) can later be measured to have a different lepton family number....
How does Super Kamiokande detect neutrinos? Beta decay in the Earth and in supernovas turns neutrons into protons with the emission of anti-neutrinos. The Super-Kamiokande detects electrons knocked off a water molecule producing a flash of blue Cherenkov light, and these...
How much did Super Kamiokande cost? Cabinet greenlights US$600-million Hyper-Kamiokande experiment, which scientists hope will bring revolutionary discoveries. How deep is the Kamioka Observatory? It is located 1,000 m (3,300 ft) underground in the Mozumi Mine in Hida’s Kamioka area. The...
What is hyper K? Hyperkalemia is the medical term that describes a potassium level in your blood that’s higher than normal. Potassium is a chemical that is critical to the function of nerve and muscle cells, including those in your heart....
What is inside the Super Kamiokande experiment? It consists of a cylindrical stainless steel tank about 40 m (131 ft) in height and diameter holding 50,000 metric tons (55,000 US tons) of ultrapure water. Mounted on an inside superstructure are about...
How does Super Kamiokande work? The Super-Kamiokande detects electrons knocked off a water molecule producing a flash of blue Cherenkov light, and these are produced both by neutrinos and antineutrinos. A rarer instance is when an antineutrino interacts with a proton...
How many neutrinos have we detected? Scientists detected 19 neutrinos from an explosion of a star inside the Large Magellanic Cloud – only 19 out of the octo-decillion (1057) neutrinos emitted by the supernova. How many neutrinos are detected per day?...
How much did Super-Kamiokande cost? Cabinet greenlights US$600-million Hyper-Kamiokande experiment, which scientists hope will bring revolutionary discoveries. What does neutrino detector do? A neutrino detector is a physics apparatus which is designed to study neutrinos. Because neutrinos only weakly interact with...
How ice cubes detect neutrinos? IceCube observes neutrinos only indirectly. The nuclear reaction made by a single neutrino produces a stream of particles that create a burst of blue light, known as Cherenkov light (see video below). This shimmering light is...
Where are the neutrinos observatories located and why? 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...
