The Super-Kamiokande Neutrino Detector
Located in Japan, Super-Kamiokande is a detector that studies the elusive particles known as neutrinos. This is a picture of the detector wall and top with about 9000 photomultiplier tubes which help detect the neutrinos

KEK test detector. This is relatively small detector built at the KEK laboratory in Japan. Its purpose is to verify how particles of a known type end energy look like in a Kamiokande-type detector. The light, short line pointing to the middle of the blue 'blob' represents track of the particle which generated light in the detector.(All images courtesy ICRR (Institute for Cosmic Ray Research), The University of Tokyo.
