| Abstract: | In this contribution we present our preliminary investigation on pulsar sensitivity of the Large Area Telescope, the main
instrument aboard the GLAST mission. In particular we concentrated our attention to pulsars located at low galactic latitudes.
We created a set of simulated pulsars having different fluxes in an array of galactic coordinates separated by a distance
greater than the LAT Point Spread Function in order to avoid confusion between adjacent sources. Galactic gamma-ray sky background
as used during the second LAT Data Challenge (DC2) is also included. We then run an automatic routine for testing periodicity for all the pulsars considering an opportune
timing solution. In this way we can obtain a map of the sensitivity of the periodic searches for different fluxes and for
various Galactic latitudes. Some assumptions have been made by simulating the pulsar sources, but this study is a first step
toward an estimate for pulsed emission sensitivity of the GLAST LAT. The pulsed flux sensitivity profile we generate could
also be input to a population synthesis code of Galactic pulsars in order to obtain more accurate predictions of the number
of expected pulsar detections by GLAST.
