The EGS (Electron Gamma Shower) computer code system is a general purpose package for the Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies from a few keV up to several TeV. It is developed at SLAC. Monte Carlo methods are a widely used class of computational algorithms for simulating the behavior of various physical and mathematical systems. ... Properties The electron is a lightweight fundamental subatomic particle that carries a negative electric charge. ... In quantum physics, the photon (from Greek ÏÏÏ, phÅs, meaning light) is the quantum of the electromagnetic field (light). ... The Stanford Linear Accelerator Center (SLAC) is a U.S. national laboratory operated by Stanford University for the U.S. Department of Energy. ...
