Particle physics telescope explodes: “The underground Super-Kamiokande Observatory in Japan detects elusive neutrino particles from space by using photomultiplier tubes to register the flashes of light they produce when they pass through a huge tank of water.

On 12 November, one of the photomultiplier tubes exploded causing a chain reaction that resulted in most of the other 11,200 light detectors also blowing up.

Scientists say the accident is a major setback, as Super-Kamiokande has produced spectacular results, helping to answer long-standing questions about the Universe. Super-Kamiokande was the very first detector to establish that neutrinos can change into different types.” BBC
