INITIAL IONIZATION DISTRIBUTION IN THE ACTIVE VOLUME OF THE IONIZATION CHAMBER
Abstract
The task of a spatial distribution of ion pairs in the active volume of the ionization fission chamber has been studied. The formula of a spatial distribution of ion pairs in cylindrical fission chambers, in which a fissile material layer is coated on the internal side of the external electrode, is derived. It is calculated in two ways: counting the number of ion pairs created in the infinitesimal volume inside the active volume of the chamber by all the trajectories, which emanate from a radiator. In the first case, the infinitesimal volume is a sphere. In the second case, it is arbitrary in shape. The formula has evaluated correctly the density of ion pairs at any point in the active volume of the fission chamber. The dependence of the initial density of ion pairs on a radial distance to a radiator created a typical fission fragment – ion Sr in the center of the chamber and the spatial distribution of the initial density of ion pairs along the chamber have been studied.
