The Canadian rare-isotope facility with electron beam ion source (CANREB) will be used for charge breeding and mass separation of rare isotope beams for experiments at TRIUMF, the Canadian National Laboratory for Particle and Nuclear Physics. The CANREB Electron Beam Ion Source (EBIS) will consist of a trapping region, electron gun, and collector, and will accept pulsed bunches of isotopes for charge breeding towards mass-to-charge ratios < 7. A software library to accurately simulate the dynamics of the injection, charge breeding, and extraction processes is being developed as a tool for engineering design and future diagnostics of the experiments. The software utilizes finite element methods to prescribe geometrical constraints, solve electrostatic and magnetostatic equations, and for self-consistent trajectory calculations of particles. Furthermore, it includes semi-empirical calculations and Monte Carlo probability to track the charge state evolution of the injected isotopes in combination with electronic structure cross-section calculations. This poster will focus on the methods employed in the software libraries and the accuracy of the calculations.
