CALET succeeds in direct
measurements of cosmic-ray
electron spectrum
up to 4.8 TeV

An international team of researchers led by Professor Shoji Torii of Waseda University, the principal investigator succeeded in extending their result from a previous study and directly measured the cosmic-ray all-electron (electron + positron) spectrum in an energy range from 11 GeV to 4.8 TeV with the Calorimetric Electron Telescope (CALET).

This study was published in online in Physical Review Letters on June 25, 2018.
