Abstract:Ionization and energy loss by minimum-ionizing particles in P10 are discussed, so as to estimate the reliability of the Geant 3.21 photo-absorbtion ionization (PAI) model implementation and to relate it to measurable ionization. Geant results are first compared to those of its parent code and found to be fairly consistent. They are then compared with the ionization distribution from an algorithm based on measurements of ionization clusters. The fitted 29.8 eV/ion pair calibration factor is larger than expected, but brings the distributions into remarkably good agreement, provided that the most probable energy loss is much larger than the ionization energy of the argon L-shell.
