Abstract

Over a decade has passed since H. H. Nagel visited SLAC and “planted the seed” to what is now called EGS (Electron Gamma Shower) ---or more appropriately, the EGS Code System. Nagel’s original program was one of three during the early 1960’s aimed at solving the electromagnetic cascade shower problem by Monte Carlo simulation (Nagel, 1963, 1964, 1965). The other two codes that were developed during this period were by Zerby and Moran (1962a,b, 1963) and by Messel and his colleagues (1962, 1970).
