Abstract
Successfully launched into a low-Earth orbit on June 11, 2008, the Fermi Large Area Telescope (LAT) is a pair conversion telescope specifically designed to survey the gamma-ray sky with unprecedented sensitivity and resolution. The broad list of exciting scientific results that the observatory has achieved in the first year of operation, though, is not limited to photon science, as it includes the first high-statistics measurement of the cosmic-ray electron spectrum for energies above 20 GeV. Here we thoroughly discuss the main aspects of the data analysis underlying this measurement and present the ongoing study aimed at lowering the energy threshold of the primary spectrum (measured by the LAT) as well as exploring the properties of the electron albedo population.
