Series arrays of about/100 superconducting-normal-superconducting junctions have been obtained in the oriented Pb-Sn lamellar eutectic alloy. The temperature and normal width dependences of the critical currents flowing through these S-N-S structures have been studied and can be explained in the framework of the Bardeen-Johnson theory for systems in the clean limit.
