CALET  

Definition

  • The CALorimetric Electron Telescope (CALET), an apparatus for observing high-energy electrons and gamma-rays, is Japan’s first full-scale project for observing cosmic rays in space. It will be launched to the International Space Station (ISS) in 2014 via Japan’s HTV-5 (Kounotori-5) transfer vehicle, where it will conduct observation of primary cosmic rays for a period of 2 to 5 years. Using equipment called a ‘calorimeter’ fitted with state-of-the-art electronic detection technology, CALET will measure the energy of particles flying through space, as well as the type of particles and their direction of arrival. We can expect these measurements to lead to new world-leading discoveries, such as the propagation and acceleration mechanisms of high-energy cosmic rays—still unexplained even now, 100 years on since the discovery of cosmic rays—as well as the search for dark matter, further elucidation of gamma-ray bursts, and more.
