Developing a software for simulation of gaseous detectors with Monte carlo method in c++ programming language

In this paper we consider a gaseous detector and supposed, because of pass of an ionizing radiation, an electron created inside it. By numerical simulation with monte carlo method and concluding the impacts, scatterings and creation of secondary electrons, we find the trajectory of initial and secondary electrons. Dependence of number of secondary electrons to applied electrical field is investigated. Finally we study the dependence of number of secondary electrons to number of initial electrons created by ionizing radiation (as a measure of the radiation energy), then we try to investigate the possibility of spectrometry by this detectors.
