The simulation relies on elementary cross sections (electron-atom and electron-molecule) and incorporates, in order to compute the gas scintillation, the reaction/quenching rates (atom-atom and atom-molecule) of the first 41 excited states of xenon and the relevant associated excimers, together with their radiative cascade. The results compare positively with observations made in pure xenon and its mixtures with CO2 and CF4 in a range of pressures from 0.1 to 10 bar. This work sheds some light on the elementary processes responsible for the primary and secondary xenon-scintillation mechanisms in the presence of additives, that are of interest to the OTPC technology. %K Optical TPCs %K Microscopic simulation %K Xenon scintillation %R 10.1016/j.nima.2017.08.049 %U http://arxiv.org/abs/1705.09481 %U https://doi.org/10.1016/j.nima.2017.08.049 %P 157-172
