Abstract
I present an updated measurement of the cosmic-ray electron and positron spectrum between 7GeV and 2TeV, based on 7 years of data collected with the Fermi Large Area Telescope (LAT). The LAT is the first space-based instrument to directly explore the region above 1TeV. The best fit to the spectrum that we measure is given by a broken power-law, with the break located at ∼ 50GeV. Above 50GeV our data are well described by a single power-law with a spectral index of 3.07 ± 0.02 (stat + syst) ±0.04 (energy scale). An exponential cutoff lower than 1.8TeV is excluded at 95% CL.
