Abstract:
The energy deposited by protons, electrons and positrons in the KASCADE GRANDE detectors is calculated with a simple and quick Monte Carlo method.
The KASCADE GRANDE experiment (Forschungszentrum Karlsruhe, Germany), based on an array of plastic scintillation detectors, has the aim to study the energy
spectrum of the primary cosmic rays around and above the "knee" region of the spectrum.
The reconstruction of the primary spectrum is achieved by comparing the data collected by the detectors with
simulations of the development of the extensive air shower initiated by the primary particle combined with detailed simulations of the detector response. The simulation of the air shower development is carried out with the CORSIKA Monte Carlo code. The output file produced by CORSIKA
is further processed with a program that estimates the energy deposited in the detectors by the particles of the shower. The standard method to calculate the energy deposit in the detectors is based on the Geant package
from the CERN library.
A new method that calculates the energy deposit by
fitting the Geant based distributions with simpler
functions is proposed
in this work.In comparison with the method based on the Geant package this method is substantially faster.
The time economy is important because the number of particles involved is large.
