A Geant4 based engineering tool for Fresnel lenses

Abstract

Geant4 is a Monte Carlo radiation transport toolkit that is becoming a tool of generalized application in areas such as high-energy physics, nuclear physics, astroparticle physics, or medical physics. Geant4 provides an optical physics process category, allowing the simulation of the production and propagation of light. Its capabilities are well tailored for the simulation of optics systems namely in cosmic-rays experiments based in the detection of Cherenkov and fluorescence light. The use of Geant4 as an engineering tool for the optics design and simulation of Fresnel lens systems is discussed through a specific example.Comment: 4 pages, 6 figures, Proceedings of the 30th ICRC, International Cosmic Ray Conference 2007, M\'erida, M\'exico, 3-11 July 200
