• Super-Kamiokande, a 15-story underground lab in Japan, detects neutrinos to study supernovae and the fundamental properties of matter.
• The detector uses 50,000 tonnes of ultra-pure water and 11,000 light detectors to observe Cherenkov radiation from neutrinos.
• Super-Kamiokande has provided strong evidence for the different behavior of matter and anti-matter, helping to explain the existence of matter in the universe.

Super-Kamiokande is a massive neutrino detector located deep beneath Mount Ikeno in Japan. This experiment aims to detect and study neutrinos, elusive subatomic particles that travel through space and matter with almost no interaction. By detecting neutrinos from supernovae and studying neutrino oscillations, Super-Kamiokande is providing insights into the universe's most violent events and the fundamental laws of physics, including the imbalance between matter and anti-matter.

• What: Super-Kamiokande is a neutrino detector designed to observe and study neutrinos, providing insights into supernovae, neutrino oscillations, and the matter-antimatter asymmetry.
• Who: Key individuals include Dr. Yoshi Uchida, Dr. Morgan Wascko (both of Imperial College London), Dr. Matthew Malek (University of Sheffield) and Neil deGrasse Tyson. Organizations involved include UC Santa Cruz and the Nobel Prize committee.
• When: The experiment has been ongoing, with notable findings regarding matter-antimatter differences being reported.
• Where: The Super-Kamiokande detector is located 1,000 meters underground beneath Mount Ikeno in Japan.

The Super-Kamiokande experiment is a significant undertaking in particle physics and astrophysics. Its ability to detect neutrinos, which interact very weakly with matter, allows scientists to probe phenomena that are otherwise inaccessible. The detector's location deep underground shields it from cosmic rays and other background radiation, enabling the detection of faint neutrino signals. The use of ultra-pure water and highly sensitive light detectors is crucial for observing the Cherenkov radiation produced by neutrinos. The findings from Super-Kamiokande have implications for our understanding of the fundamental laws of physics and the evolution of the universe.

Matter poses no obstacle to a neutrino. A neutrino could pass through a hundred light-years of steel without even slowing down.

If there’s a supernova, a star that collapses into itself and turns into a black hole… if that happens in our galaxy, something like Super-K is one of the very few objects that can see the neutrinos from it.

Pure water is very, very nasty stuff. It has the features of an acid and an alkaline.

Super-Kamiokande is a cutting-edge neutrino detector playing a crucial role in advancing our understanding of the universe. By detecting elusive neutrinos, the experiment provides insights into supernovae, neutrino oscillations, and the matter-antimatter asymmetry. Ongoing research and upgrades to the detector promise further discoveries in the years to come.
