Alpha Particles ionization simulation using GEANT4
GEANT4 simulates the ionization of alpha particles in Ar/CO2 90/10 gas. Geant4 can simulate the ionization process for the alpha particles, but unfortunately the value of the step function of the step function that determines the number of delta electrons is very low even by decreasing the cut to 1 nm. Also Range of alpha particles in Ar/CO2 gas is not accurate and does not match the projected ranges using srim File:Alpha range ArCo2.txt, the following table shows the maximum range of the alpha particles that are emitted from the U-233, and the ranges calculated by srim.
