Description
The transportation of ions in matter is subject of much interest in not only
high-energy ion-ion collider experiments such as RHIC and LHC but also many
other field of science, engineering and medical applications. Geant4 is a tool
kit for simulation of passage of particles through matter and its OO designs
makes it easy to extend its capability for ion transports. To simulate ions
interaction, we had to develop two major functionalities to Geant4. One is
cross section calculators and the other is final stage generators for ion-ion
interactions. For cross sections calculator, several empirical cross section
formulas for the total reaction cross section of ion-ion interactions were
investigated. And for final stage generator, binary cascade and quark-gluon
string model of Geant4 were improved so that ions reaction with matter can also be
calculated. Having successfully developed both functionalities, Geant4 can be
applied to ion transportation problems. In the presentation we will
explain cross section and final stage generator in detail and show comparisons with
experimental data.
