Cosmic-ray electrons provide a probe of the origin and propagation mechanisms of cosmic rays in local galactic environment
The Large Area Telescope (LAT), on board the Fermi mission, is a pair-conversion space telescope for high-energy electromagnetic radiation, operating in low Earth orbit since June 2008. The LAT has collected the largest high-energy cosmic-ray electron sample to date, with more than 10k events above 1 TeV. The event selection and reconstruction capability exploits the performance of the recently improved event-level analysis developed by the Fermi-LAT Collaboration.
We present a new measurement of the inclusive spectrum of cosmic-ray electrons and positrons performed on seven years of data, in an energy range from 7 GeV up to 2 TeV.
