STARDUST: A Code for the Simulation of Particle Tracks on Arrays of Sensitive Volumes With Substrate Diffusion Currents

This paper describes STARDUST, a new Monte Carlo code dedicated to the simulation of particle tracks on imaging detector arrays. The geometrical detector model, the particle parameters sampling method, the particle tracking and energy deposition and, finally, the carrier collection by diffusion currents in the substrate are described in detail. Some examples of simulations are given at the end, together with a comparison between COROT satellite data and simulation results.
