Detection of Gamma-Ray Bursts in the 1 GeV - 1 TeV energy range by ground based experiments

Abstract

Ground based extensive air showers arrays can observe GRBs in the 1-1000 GeV energy range using the "single particle" techique. The sensitivity to detect a GRB as a function of the burst parameters and the detector characteristics are discussed. The rate of possible observations is evaluated, making reasonable assumptions on the high energy emission, the absorbtion of gamma-rays in the intergalactic space, the distribution of the sources in the universe and the bursts luminosity function. We show that a large area detector located at high mountain altitude has good prospects for positive detections, providing useful informations on the high energy components of GRBs.
