Paper Abstract

Since its launch on June 11, 2008 the Fermi Large Area Telescope (LAT) has been exploring the gamma-ray sky at energies from 20 MeV to over 300 GeV. Five years of nearly flawless operation allowed a constant improvement of the detector knowledge and, as a consequence, continuous update of the event selection and the corresponding instrument response parametrization. The final product of this effort is a radical revision of the entire event-level analysis, from the event reconstruction algorithms in each subsystem to the background rejection strategy. The potential improvements include a larger acceptance coupled with a significant reduction in background contamination, better angular and energy resolution and an extension of the energy reach below 100 MeV and in the TeV range. In this paper I will describe the new reconstruction and the event-level analysis, show the expected instrument performance and discuss future prospects for astro-particle physics with the LAT.
