AB  - The precise modeling of proton therapy systems is challenging and requires simulation tools that have capabilities in both beam transport and in the detailed description of particle-matter interactions. Current separate simulations such as those of optical codes or Monte-Carlo transport through discrete elements show their limitations due to the very strict requirements on beam quality at the isocenter. This is particularly relevant with the development of compact systems where the coupling between the components is dominant. For such systems the design of the concrete shielding, which has a large impact on the total cost of the system, is of primary importance. Beam Delivery Simulation (BDSIM) allows the seamless simulation of the transport of particles in a beamline and its surrounding environment. A complete 3D model is built using Geant4, CLHEP and ROOT to provide an extensive insight into beam loss, its interaction and subsequent radiation. This capability is applied to the IBA eye treatment proton therapy machine and to the IBA Proteus One compact system. We discuss the validation of both models against experimental data. In particular, we use it to predict lateral profiles and energy spectra using a detailed geometry of the eye-treatment beam forming nozzle. For the Proteus One system, we present results on the activation of the concrete shielding of the system estimated for a period of 20 years of operation obtained for the first time using end-to-end simulations of the transport of protons in the beamline and their interactions with the environment.
