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.

How much did Super-Kamiokande cost?

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

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 in water to produce a neutron and a positron.

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 you visit Kamioka Observatory?

The entrance to KamiokaLab. Admission is free. The unusually named Kamiokande and Super Kamiokande observatories gained international renown first in 2002, when Koshiba Masatoshi won the Nobel Prize for physics for his discoveries there, and then again in 2015, when Kajita Takaaki was similarly honored.

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.

Where is the largest neutrino detector located?

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.

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.

Why are neutrino detectors built deep underground?

Because neutrinos only 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.

How do people detect neutrinos?

So how do you detect a neutrino? One common way is to fill a big tank with water. We know light slows down through water, and if a neutrino with enough energy happens to knock into an electron, the electron will zip through the water faster than the light does.

What neutrino means?

A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are one of the most abundant particles in the universe.

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.

How does the Sudbury Neutrino Observatory work?

The experiment observed the light produced by relativistic electrons in the water created by neutrino interactions. As relativistic electrons travel through a medium, they lose energy producing a cone of blue light through the Cherenkov effect, and it is this light that is directly detected.

Why does neutrino oscillation imply mass?

The reason neutrino oscillation is relevant to the question of neutrino mass is that massless neutrinos cannot oscillate. The observation of oscillation implies that the masses of the neutrinos involved cannot be equal to one another. Since they cannot be equal to one another, they cannot both be zero.
