The CALET Project for International Space Station
Abstract
The CALorimetric Electron Telescope CALET mission is proposed for the observation of various components of cosmic-rays as well as gamma-rays at the Exposure Facility of Japanese Experiment Module on the International Space Station The detector is composed of an imaging calorimeter of scintillating fibers IMC and a total absorption calorimeter of BGO TASC The total thickness of absorber is 36 r l for electromagnetic particles and 1 8 m f p for protons The total weight of payload is nearly 2 500 kg and the geometrical factor for the electrons is about 1 m 2 sr The CALET has a unique capability to measure the electrons and gamma-rays beyond 1 TeV since the hadron rejection power can be 10 6 for electrons and much better for gamma-rays The energy resolution for the electro-magnetic particles is better than a few above 100 GeV The detector is optimally designed to detect any change of energy spectra caused by physical processes or the line signature in the energy distribution expected from annihilations of dark matter candidates We will discuss CALET including its technique its exposure and its status at that time as well as its science
