Can you visit Super-Kamiokande?

Can you visit Super-Kamiokande?

From the viewpoint of safety management in the mine, individual tours are not permitted as a general rule. However, for educational and research-related organizations, visits may be accepted after coordination.

Where is the largest neutrino detector?

IceCube is a state-of-the-art neutrino telescope at the geographical South Pole, buried deep under the surface of the Antarctic ice cap. With more than five thousand optical sensors distributed over a cubic kilometer of ice, IceCube is the biggest particle detector world-wide.

Where is the Super-Kamiokande experiment?

Super-Kamiokande is located 1000 m underground in the Kamioka mine, Gifu prefecture, Japan. The horizontal entrance tunnel leads us to the experimental area through 1.7 km drive, which allows us to access the detector for 24 h for maintenance.

Can we detect neutrinos?

Billions of them pass through us every second—mostly coming from our sun. But unlike the sunlight we can easily see, neutrinos are very hard to detect. To “see” them, we have to build really big detectors and block out signals from any other particles. Scientists do that by building neutrino detectors deep underground.

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 13,000 photomultiplier tubes that detect light from Cherenkov radiation.

How do you catch neutrinos?

A neutrino is able to react with an atom of gallium-71, converting it into an atom of the unstable isotope germanium-71. The germanium was then chemically extracted and concentrated. Neutrinos were thus detected by measuring the radioactive decay of germanium.

How much did Super Kamiokande cost?

Cabinet greenlights US$600-million Hyper-Kamiokande experiment, which scientists hope will bring revolutionary discoveries.

Can neutrinos be weaponized?

In other words, no you cannot sensibly weaponise neutrinos, they just don’t have enough affect on anything you care about.

How far can a neutrino travel?

Neutrinos are subatomic particles that have almost no mass and can zip through entire planets as if they are not there. Being nearly massless, neutrinos should travel at nearly the speed of light, which is approximately 186,000 miles (299,338 kilometers) a second.

Who solved the solar neutrino problem?

The solar neutrino problem was solved on June 18, 2001 [1] by a team of collaborative Canadian, American, and British scientists. The results came from an experiment in a detector full of 1,000 tons of heavy water (D2O, or wa- ter composed of deuterium in place of hydrogen.

What is a neutrino burst?

Supernova neutrinos are produced when a massive star collapses at the end of its life, ejecting its outer mantle in an explosion. Wilson’s delayed neutrino explosion mechanism has been used for 30 years to explain core collapse supernova.

How deep is the Kamioka Observatory?

Buried 1 kilometer underground near the city of Hida in central Japan is an enormous cylinder 40 meters tall and filled with 50 million liters of water.

Are neutrinos dark matter?

Neutrinos are one candidate for dark matter but only if they have a nonzero rest mass. Neutrinos interact only via the weak force and gravity which would explain we don’t see dark matter can’t be detected through interactions with light like baryonic (normal) matter.

Can anything stop neutrinos?

“We knew that lower-energy neutrinos pass through just about anything,” Cowen said, “but although we had expected higher-energy neutrinos to be different, no previous experiments had been able to demonstrate convincingly that higher-energy neutrinos could be stopped by anything.”

What can neutrinos tell us?

Neutrinos could help us identify other forces in the universe that we have not yet been able to detect or understand. They can teach us about the core of the densest stars, and could one day lead to the discovery of new astrophysical objects.

How many Neutrino Observatory are there in the world?

There are about 20 or so neutrino detectors, telescopes, and experiments around the world.

Where is the largest particle collider?

The Large Hadron Collider (LHC) is the most powerful particle accelerator ever built. The accelerator sits in a tunnel 100 metres underground at CERN, the European Organization for Nuclear Research, on the Franco-Swiss border near Geneva, Switzerland.

How big is the IceCube Neutrino Observatory?

IceCube, the South Pole neutrino observatory, is a cubic-kilometer particle detector made of Antarctic ice and located near the Amundsen-Scott South Pole Station. It is buried beneath the surface, extending to a depth of about 2,500 meters.

How many neutrinos are detected per day?

IceCube detects 275 atmospheric neutrinos daily and about 100,000 per year. About 350 scientists at 58 institutions in 14 countries conduct IceCube science (as of October 2022).
