The GLAST Large Area Telescope (LAT) is the next generation satellite experiment for high-energy gamma-ray astronomy. It employs a pair conversion technique to record photons in the energy range from 20 MeV to 300 GeV and higher. Its modular design consists of sixteen towers made of silicon trackers followed by segmented CsI electromagnetic calorimeters. Towers are surrounded by plastic scintillators acting as an anticoincidence shield that rejects unwanted charge particle background. The LAT will follow the steps from its predecessor, EGRET, and will explore the high energy gamma-ray sky with unprecedented capabilities.
The detection and observation of Gamma-Ray Bursts is one of the main scientific goals of the LAT. A full simulation chain has been developed by the LAT collaboration, starting from the simulation of the source to the detailed Montecarlo simulation of the instrument, and to the full reconstruction software. Analysis tools dedicated to the GRB science have been developed, as well as the simulation of the GLAST Burst Monitor, the second instrument on-board GLAST, dedicated to GRB's. In this contribution we show the expected LAT sensitivity obtained with such simulations, as well as some results from spectral and temporal analysis.
