摘要：

In this study, the prompt gamma-rays (PGs) produced during the interactions of proton beams of various energies have been investigated using the MCNPX2.6 Monte Carlo code. Having considered a detection setup consisting of a thick lead collimator and a commercial plastic scintillator, the event-by-event data, generated by the PTRAC card of the MCNPX code, when the scintillator is exposed to PGs have been extracted before they are used in a dedicated light transport code, PHOTRACK. The plastic scintillator response when it is moved along the phantom axis determines the flux variation of proton-induced PGs which can be further related to the longitudinal deposition energy profile of protons, i.e., the Bragg curve. The present study shows that the Bragg peak location is similar to 3.7 cm after the PG peak for different proton energies of interest. The uncertainty in the Bragg peak location data is about 0.02 cm which can be improved by taking into account the precise electron-transport simulation details.
