Comparison of calculation of energy deposition parameters with experimental results

A comparison of the main parameters of spatial distribution of energy deposition was performed for two codes predictions (MARS and RTS&T) and experimental data for 1 GeV protons incident on targets composed of beryllium, carbon, aluminium, iron, copper, lead, bismuth, and tungsten. In general, calculations show a good agreement with data, but no definable trend could be determined for materials because some code predictions were higher and some lower than the experimental results. Parametrization can be used for quick modelling by the MC FAST method for radiation therapy and proton radiography, and in high-energy physics for the calculation of hadron calorimeteres.
