Abstract :
Long Josephson junctions with edge current injection and shortened control lines are studied experimentally. It is found that the wall effect is connected with the blockage of vortices entry into the junction by control current, as well as with the existence of the energy barrier for the vortices at the boundary between a projection region and the remaining portion of the junction. Significant enhancement of supercurrent due to the blockade was found
