We investigate the Kibble-Zurek mechanism of creation of topological defects in a superconducting hollow cylinder ("ring") undergoing phase transition from the supercooled normal state. Solving numerically the set of the time-dependent Ginzburg-Landau (TDGL) equations, we show the evolution of the spontaneously created topological vortices and antivortices inside the superconducting ring. It is shown that the Josephson weak links in the ring can significantly increase the spontaneous flux trapped in the ring's hole.
