Özet

This study presents the results of Monte Carlo simulations to obtain stopping power of protons in energy ranges and materials of therapeutic importance. The source was modeled as a point source emitting mono-energetic pencil beam of protons. A cylinder containing the material of interest was placed in vacuum to represent the phantom, a cylinder of 30 cm radius and 100 cm height. A disk-shaped thin detector (r=2 cm) was created in this phantom to compute average values of absorbed dose and flux. Its thickness varied from simulation to simulation depending on the energy of the incoming source protons. Average flux and absorbed dose were computed in the detector cell to evaluate the value of the stopping power for the material of interest at that specific energy. The results obtained in this study arc compared with the data from the NIST compilation.
