Description
We summarize the results of simulation studies of the propagation of cosmic ray air shower cores through high-altitude polar ice sheets, using the COSIKA 7.7100 Monte Carlo code and the Geant4 10.5 simulation toolkit. We discuss the general characteristics of the in-ice particle cascade, including the energy density deposted in the ice, the longitudinal development of the shower, and the radial distribution of the charged particles in the ice as a function of Xmax of the shower. We present preliminary calculations of the Askaryan radio emission of the in-ice particle cascade using the end-point formalism, showing that they may resemble the Askaryan radiation of in-ice neutrino-induced particle cascade. Finally, we discuss the possibilty of detecting the plasma created in the ice by comsic ray air shower cores using RADAR echo techniques.
