TODO - A theoretical model of self-focusing of an impulse electron beam in a two-layered superconducting tube is designed. The self-focusing force is calculated and, by defining the pair breaking time of the superconducting pair, it is shown that this is conditioned among others by the ratio of the beam pulse period to the pair breaking time. The model is validated by evaluating both the breaking time and the focusing length.
