[24.03] GLAST Large Area Telescope Instrument Integration and Science Preparation

J. E. Grove (NRL), J. E. McEnery (GSFC), GLAST LAT Collaboration

The Large Area Telescope (LAT), under construction for launch by NASA in 2007 on the Gamma-ray Large-Area Space Telescope (GLAST) mission, will survey the sky in the energy range from 20 MeV to >300 GeV. The detector subsystems of the LAT -- a pair-conversion tracker, a scintillating crystal calorimeter, and a plastic scintillator anticoincidence shield -- will provide much greater angular resolution, effective area, and field of view for gamma rays than the highly successful EGRET detector on the Compton Gamma-Ray Observatory. The detector subsystems have been completed, integration of the LAT instrument is in its final stages, and a program of test data taking with the LAT has begun. Concurrently, an extensive program of science analysis software development is underway, driven by a series of data challenges that span from low-level event reconstruction through generation of astrophysically interesting quantities, e.g. spectra, lightcurves, sky maps, etc. Here we summarize the LAT integration status, test data taking -- including first photons -- and science tool preparation.
