Fig. 5From: Adaptive step size algorithm to increase efficiency of proton macro Monte Carlo dose calculationInvestigation of lateral material interface. Integrated depth dose curves for a mono-energetic proton pencil beam (125 MeV) impinging parallel to a material interface at a lateral distance of 0.1 mm. Lines are for the adaptive pMMC (dashed), adaptive pMMC without step size restriction (dotted) and full Monte Carlo with Geant4 (solid)Back to article page
