One-dimensional Hybrid Simulation of EAS Using Cascade Equations

Abstract A hybrid simulation code is developed that is suited for fast one-dimensional simulations of shower profiles, including fluctuations. It combines Monte Carlo simulation of high energy interactions with a fast numerical solution of cascade equations for the resulting distributions of secondary particles. First results obtained with this new code, called CONEX, are presented and compared to COR-SIKA predictions, focusing on the treatment of the electromagnetic shower component
