Background Radiation Studies at LHCb using Geant4
This paper aims to describe the feasibility studies
performed to evaluate the background radiation levels in the
LHCb experiment with Geant4. LHCb is one of the experiments
that will operate at the LHC (Large Hadron Collider) under
construction at CERN. The simulation toolkit Geant4 has been
used to model the interactions of particles with the detector.
Geant4 is a software toolkit developed and maintained by a
world-wide collaboration of physicists and computer scientists.
The principal monitored distributions in this study are the dose
and the fluence of certain particles in specific locations of the
experiment. The dose is defined as the energy delivered in a
volume per unit of the volume mass, while the fluence is defined
as the number of particles passing through a surface per unit of
area. Energy spectra need also to be evaluated to take into
account the energy distribution of these particles, since specific
problems in the electronics can be caused by particles of certain
energies.
For this purpose, we need to tally doses and fluences using
Geant4.
The 2D mapping of doses and fluences of charged hadrons,
neutrons, gammas, electrons and positrons on planes put in
specific critical areas, where the electronics is located, have been
obtained.
Geant4 provides different physics models to describe interaction
processes allowing customization of the simulation engine to
specific problems. Preliminary results using different relevant
physics models are presented.
