Аннотация: The dependence of the critical current Ic, i.e. the current that starts the motion of vortices in a one-dimensional long (WGtlambda4J) Josephson junction, upon the external magnetic field H is found. Various positions for input electrodes were considered, viz. when the external current is fed from the extremities of the junction, through one or more middle points uniformly distributed along the junction. It is shown that in the two last cases the value of Ic may substantially exceed the value of 2JclambdaJ that corresponds to the first critical field.
