How much does a neutrino detector cost?
Building the detector is expected to cost ¥64.9 billion, about US$600-million, says Masato Shiozawa, a neutrino physicist at the University of Tokyo and the project’s co-leader.
Where Super-Kamiokande neutrino detector is located?
Mount Ikeno
Super-Kamiokande (abbreviation of Super-Kamioka Neutrino Detection Experiment, also abbreviated to Super-K or SK; Japanese: スーパーカミオカンデ) is a neutrino observatory located under Mount Ikeno near the city of Hida, Gifu Prefecture, Japan.
Has a neutrino been detected?
For the first time ever, researchers have detected neutrino candidates produced by the Large Hadron Collider (LHC) at the CERN facility near Geneva, Switzerland.
Why is neutrino detection so difficult?
Why are neutrinos so hard to detect? Neutrinos are very hard to detect because they have no electric charge. But when a neutrino passes through matter, if it hits something dead-on, it will create electrically charged particles. And those can be detected.
Why are neutrinos so hard to detect?
Are neutrinos faster than light?
Neutrinos are tiny, electrically neutral particles produced in nuclear reactions. Last September, an experiment called OPERA turned up evidence that neutrinos travel faster than the speed of light (see ‘Particles break light speed limit’).
How much did Super-Kamiokande cost?
”Japan paid for most of the $100 million construction cost of Super-Kamiokande, and the United States put up less than 10 percent, and yet American physicists make up half the research force. We hope the Japanese Government will allow uninterrupted operation of this great scientific instrument. ”
Can you visit Super-Kamiokande?
Our researchers will guide you around the underground research area of Super-Kamiokande and KAGRA in English. Ask any questions you have through YouTube Live Chat. We will be hosting a series of live SK/KAGRA Virtual Open Days on November 22-23, 2020.
How do you identify a neutrino?
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.
How many neutrinos have been detected?
19 neutrinos
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.
Where can you find neutrino detectors in Japan?
Located in the cool depths of a mine, in the heartlands of central Japan, the design of this neutrino detector is mind-boggling. In fact, you won’t believe your eyes. Total adventure. I’ll take you there? OK, let’s explore Super-Kamiokande! The detector is cleaned once every ten years or so.
Can atmospheric neutrinos be detected in Kamiokande-II?
The flux of atmospheric neutrinos is considerably smaller than that of the solar neutrinos, but because the reaction cross sections increase with energy they are detectable in a detector of Kamiokande-II’s size.
What is the Kamioka Observatory?
The Kamioka Observatory, Institute for Cosmic Ray Research (神岡 宇宙 素粒子 研究 施設, Kamioka Uchū Soryūshi Kenkyū Shisetsu, Japanese pronunciation:) is a neutrino and gravitational waves laboratory located underground in the Mozumi Mine of the Kamioka Mining and Smelting Co.
What is the Super Kamiokande detector?
The Super Kamiokande detector was designed to test the oscillation hypothesis for both solar and atmospheric neutrinos. The Super-Kamiokande detector is massive, even by particle physics standards. It consists of 50,000 tons of pure water surrounded by about 11,200 photomultiplier tubes.
