Abstract
We recall the theoretical bases necessary to model micro fission chambers operated in current mode. For these detectors, we propose formulae for the lower and upper limits of the saturation zone, obtained through analytical and numerical resolutions of the charge transport equations. Using these results, we calculate the voltage extension of the saturation plateau, as function of parameters such as the electrode geometries or the characteristics of the filling gas.
