โฆ Synopsis
radial components of the external field, flowing perpendicular to the shield generator. Cutting the ribbon into strips gives rise to a current flowing in the strip parallel to the generator. This current is the greater relative to the shield-~ 0.8 ing current, the narrower the strip. This leads to reaching -~ the critical current in smaller fields than in shields of solid fxl

Amplitude of the Coulomb blockade oscillations is calculated for a single-mode Josephson junction with large electron transparency D. It is shown that the Coulomb blockade is suppressed as D + 1. The suppression is described quantitatively in terms of the Landau-Zener transition in imaginary time.
