Numerical modelling: The physical model for the simulation of the
primary and secondary cosmic-ray particles is based on systems of
general purpose Monte Carlo computer codes (e.g. LAHET, MCNP) that
treat relevant physical processes of particle production and transport.
The calculated production rates will be compared to measurements of the
natural and artificial target networks as well as the cross-calibration
sites. The comparison will enable us to adjust reaction cross sections
for which good measurements do not exist.
Deliverables of the numerical modelling will be the unification of
the target measurements into either general purpose scaling factors, or
if required specific scaling factors for each TCN. The modelling will
achieve the physics-based interpolation between the points of the
scaling grid and the cross calibration sites. Model calculations
similar to those outlined above have been published by participating
network members and currently define the state of the art (e.g. Masarik
and Beer 1999; Masarik et al. 2001).
