About


The IBIC Simulation Tool (IST) is a software with graphical user interface for the simulation of 1-dimensional IBIC experiment. The software is based on the Monte Carlo solution [1] of the continuity equation for excess charge carriers. The IST allows to interface with external electrostatic models, ionization and vacancy density profiles and produces real-time total and time-resolved charge collection efficiency (CCE) pulses, statistical profiles, spectra. The IST also provides a model for the carriers' lifetime degradation in irradiated devices, describing the linear decrease in CCE in low damage regime and providing a quantitative description of the radiation hardness parameter k. For an updated list of scientific publications and presentations introducing and exploiting the IST is available here. The software is currently available in beta version from this webpage.
