Update on Corsika Simulation 15 June 2015 Fabrizio Coccetti
Choice of Models for Hadronic Interactions After talking with experts (Lorenzo Perrone and Daniele Martello), we decided which models should be used to generate showers for EEE: High-energy Hadronic Interactions: EPOS (this is the only model available in Corsika which reproduces heavy ion data from RHIC *and* LHC ) Low-energy Hadronic Interactions: FLUKA (standard choice)

Configuration Energy Cuts (Same as ARGO) ECUTS 0.05 0.05 0.00005 0.00005 (GeV) Hadrons, Muons, Electrons, Photons The low energy cut-off of the particle kinetic energy
Configuration Observation Level (Sea level) OBSLEV 0.E2 (cm)
Configuration magnetic field (Rome) MAGNET 24.5 39.4 24.5: is the horizontal component of the Earth’s magnetic field (in μT) to the x-direction of the detector (North) 39.4: is the vertical component of the Earth’s magnetic field (in μT) downwards.
A python package to use Corsika to generate showers on multiple CPUs e3sim is a python package written to perform simulations for the (Extreme Energy Events) EEE experiment. Available on: github.com/centrofermi Multithreading is supported: You have just to specify the number of cores you want to use and the software take care of generating different threads in different cores/CPUs.
