We present an analytical solution for the nonlinear equation of motion of an electron beam in the radial direction of a superconducting tube, for the case of electrons moving close to the tube axis. Accordingly, we deduce a general expression for the focusing length dependence on the parameters of the superconducting tube and the electron stream. Our calculated focusing length is in good agreement with the experimental data.
