Comparison of EGS5 simulations with experiment

摘要

Simulations, made using EGS5, of the longitudinal and radial distributions of energy deposition of electrons of various energies are compared with experimental results in the literature. Energies and materials are: 1 GeV in water and aluminum; 6 GeV in aluminum, copper and lead; and (longitudinal only) 28.5 GeV in alumina (Al_2O_3). There is general agreement within a few percent over most of the shower profile. Substantial discrepancies are noted at depths far beyond shower maximum, reaching ～30-50% in the cases of lead and copper at 6 GeV.
