Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 927, 125–132. doi:10.1016/j.nima.2019.02.0130168-9002https://hdl.handle.net/10347/39390ACTARSim is a framework based on Geant4 and ROOT to simulate the response of active targets for nuclear physics experiments with radioactive beams. In this paper, we present the performance of the simulations for the energy-loss profile, total energy, range and angular resolution of the reconstructed track. Validation of the ACTARSim software against experimental data was performed in iC4H10 with a mixed alpha source using the ACTAR TPC demonstrator. The results show a good agreement with the simulations indicating the validity of the models used in ACTARSim for -particles in iC4H10.eng© 2019 Elsevier B.V.
