Title: A Study on Heavy Ion Beam Simulation using Geant4
Abstract:
We introduce the result of the heavy-ion beam simulation on Geant4 toolkit that is the most accurate simulation packages
for particle-material interactions. We compare our simulation results with experimental data on heavy-ion beams.
We determine the optimized simulation toolkit and its parameters for these experiments. We also provide the relevant
references for various issues arising in our study. We simulate the interaction of particles with target material and study
the characteristics of heavy-ion beams. As regards study design, first, we examine the validity of the Geant4 model.
Next, we examine the various physics models built in the Geant4 to determine the most optimized model that describes
the expected physical phenomena. Finally, we execute the Geant4 simulations to determine the characteristics of secondary
heavy-ion beams. We plan to use these results for Rare isotope Accelerator complex for ON-line experiment (RAON), which
is an upcoming facility for heavy-ion collision experiments in Korea.
