HIGH-ENERGY PHYSICS:
Shock Wave May Have Knocked Out Japanese Neutrino Detector

TOKYO--The tank was three-quarters full on the morning of 12 November when the technicians in the control room of the $100 million Super-Kamiokande neutrino observatory heard a roar that lasted half a minute or more. When it was over, all the finely tuned light-detecting sensors below the water had imploded, and the observatory lay crippled. It may be 2007 before the facility is back at full capacity, and repairs could cost $15 million to $25 million, but scientists and government officials have vowed to resume some experiments within a year.
