Observing GRBs with the GLAST LAT Telescope

The Gamma-ray Large Area Space Telescope (GLAST) is the next generation satellite for high-energy gamma-ray astronomy. The main instrument, the Large Area Telescope (LAT) is a pair conversion telescope built with a high precision silicon tracker, a segmented CsI electromagnetic calorimeter and a plastic anticoincidence shield. The LAT will survey the sky in the energy range between 20 MeV to more than 300 GeV. The huge field of view, large collection area, broard spectral coverage and good angular resolution make the LAT ideally suited to a study of the high energy gamma-ray emission from GRB. Analysis and simulation tools dedicated to the GRB science have been developed, including simulation of the GLAST Burst Monitor (GBM), the second instrument on-board GLAST. In this contribution we show the expected LAT sensitivity obtained with such simulations, and illustrate the results we expect from LAT observations with spectral and temporal analysis of simulated GRB.
