The penetration of screening currents induced in a hollow superconducting cylinder exposed to a transverse magnetic field is calculated two-dimensionally using a numerical model which simulates the superconductor by a system of parallel wire~ Assuming the critical state model and taking account of t
It is shown that in a structure consisting of a superconducting ring-shaped electrode overlapped by a normal metal contact through a thin oxide barrier, measurements of the tunnel current in magnetic field can probe persistent currents in the ring. The effect manifests itself as periodic oscillation
