Abstract

AlfaMC is a Monte Carlo simulation code for the transport of alpha particles. The code is based on the Continuous Slowing Down Approximation and uses the NIST/ASTAR stopping-power database. The code uses a powerful geometrical package allowing the coding of complex geometries. A flexible histogramming package is used which greatly easies the scoring of results. The code is tailored for microdosimetric applications where speed is a key factor. Comparison with the SRIM code is made for transmitted energy in thin layers and range for air, mylar, aluminum and gold. The general agreement between the two codes is good for beam energies between 1 and 12 MeV. The code is open-source and released under the General Public Licence.
