PROPOSAL as a tool for the calculation of electromagnetic and muonic energy losses — •Maximilian Sackel, Jean-Marco Alameddine, and Jan Soedingrekso — Technische Universität Dortmund, Dortmund, Germany

For cosmic rays experiments, precise simulations of the various components of a particle shower are of high importance. Both the muonic and the electromagnetic component of an air shower can be propagated with the lepton propagator PROPOSAL. The initial concept was to calculate the energy losses of muons in large volume media with constant density. For the propagation of the muonic and electromagnetic shower components through inhomogeneous densities, modifications are needed that preserve the modularity to new interactions and parameterizations. Fast propagation is ensured by the use of interpolation tables, whereby the number of calculated tables is kept as small as possible by parameterizing the density distribution of the media. On the basis of the air shower simulation program CORSIKA a concept is shown how stochastic and continuous interaction points can be calculated with the library PROPOSAL for the use in a custom simulation.
