Damaged neutrino detector 'Super Kamiokande' restored

GIFU, Japan - A large neutrino detector operated by the University of Tokyo's Institute for Cosmic Ray Research (ICRR) in Gifu Prefecture is shown off to the media Sept. 24 after it was repaired following severe damage sustained in an accident in November 2001. About 7,000 or 60% of the 11,000 photomultiplier tubes (PMTs) attached to the neutrino detector in the town of Kamioka in the central Japanese prefecture were found broken last Nov. 12 due to a chain reaction, but it is now repaired to a level that experiments can resume, ICRR officials said.

Japanese, U.S. physicists to share Israel's Wolf Prize

TOKYO, Japan - Masatoshi Koshiba, professor emeritus at the University of Tokyo who will share the 2000 Wolf Prize in physics with a U.S. scientist, is shown in a file photo. The Israel-based Wolf Foundation said on Jan. 18 Koshiba, 73, and Raymond Davis Jr., 85, a professor at the University of Pennsylvania, will share the 100,000 dollar prize, to be presented in Jerusalem in May. Koshiba has led a series of experiments on neutrinos, using the Kamiokande and Super-Kamiokande detectors in the town of Kamioka, Gifu Prefecture, to study the subatomic particles emitted by supernovas.

Study shows neutrinos possess m

A team of Japanese and U.S. scientists have found evidence showing for the first time that neutrinos -- tiny, electrically neutral, subatomic particles -- possess mass, contradicting the standard theory of particle physics. The Super-Kamiokande group made the finding by using a 50,000-ton tank (in the photo) of highly purified water located about 1,000 meters underground in the Kamioka Mine in Gifu Prefecture, central Japan. ==Kyodo
