Abstract A subroutine package, GENAS, is presented which enables the user to generate air showers induced by gamma rays, protons, or heavy primaries ranging from 10^(13)eV to 10^(20)eV. GENAS is capable of producing air showers very rapidly while keeping the quality of the showers as if they were produced by the full Monte Carlo method. It includes the response of detectors consisting of a plastic scintillator under thin iron and an optional lead sheet. GENAS offers a means for investigating sur... Title of program: GENAS V2.1 Catalogue Id: ABZN_v1_0 Nature of problem Point sources emitting high energy gamma rays (>10^13 eV) are normally studied with surface air shower arrays which usually employ plastic scintillator detectors. We need a reliable Monte-Carlo code to simulate air shower observation, by which simulation a quantitative comparsion with experiment should be possible for knowing or improving array performance. Every quantity needed for the simulation is, in principle, a function of the primary particle type, energy, zenith angle, age of the shower ...
