1. Update on Corsika Simulation 15 June 2015
Fabrizio Coccetti

2. 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)

3. Configuration EPOS Parameters
EPOPAR input ../epos/epos.param !initialization input file for epos
EPOPAR fname inics ../epos/epos.inics !initialization input file for epos
EPOPAR fname iniev ../epos/epos.iniev !initialization input file for epos
EPOPAR fname initl ../epos/epos.initl !initialization input file for epos
EPOPAR fname inirj ../epos/epos.inirj !initialization input file for epos
EPOPAR fname inihy ../epos/epos.ini1b !initialization input file for epos
EPOPAR fname check none
EPOPAR fname histo none
EPOPAR fname data none
EPOPAR fname copy none

4. Configuration Energy Cuts (Same as ARGO)
ECUTS
(GeV)
Hadrons, Muons, Electrons, Photons
The low energy cut-off of the particle kinetic energy

6. 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.

7. 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.
