Abstract

We ne developing a new telescope, named FIGARO IV, for $\gamma$ -ray astronomy above 100 MeV, in which the electron-positron pair, produced by photon in lead converters, are tracked in several independent planes of Limited Streamer Tubes (LST). Beeause of its large sensitive area and good angular resolution, this telescope is well suitable, and competitive with respect to satellite based detectors as EGRET, to localise discrete $\gamma$ -ray sources in a relatively short observation time, to detect high energy $\gamma$ -ray bursts and to investigate both periodic and random time variability on $\gamma$ -ray sources.
In this contribution we present the results on the imaging performances, evaluated by means of many numerical simulations based on the GEANT 3.15 code, for a 16 m^2 telescope, as FIGARO IV that we project to fly by means of a stratospheric balloon.
PACS 98.70.Rz - $\gamma$ -ray sources.
