Modeling of electromagnetic showers in ice at E ∼ 1 TeV

Abstract. We use a GEANT based Monte Carlo simulation to investigate the properties of electron induced electromag-netic showers in ice. Various shower parameters such as crit-ical energy, Moliere radius, and track lengths are studied. We look at the dependence of these quantities on the energy of the primary electron as well as the Monte Carlo threshold energy. We also study in detail the Cerenkov radiation asso-ciated with the charge excess in the shower. The radiation is coherent at frequencies on the order of GHz and can readily be detected by experiments such as the RICE at the South Pole.
