The introduction of pulses into the cable and the extraction of pulses from it were accomplished by means of pulse transformers based on ferrite cores built directly into the coaxial cable in such a way that the central conductor was used as the turn on the secondary or primary winding. This circuit was used to accomplish recirculation of a pulse 12 nsec long in a superconducting coaxial cable 100 m long with an inner conductor of Nb wire 0. 26 mm in diameter and an outer conductor consisting of a Pb sheath 2. 2 mm in diameter; the insulation consisted of Teflon. The wave impedance of the cable was 75 OMEGA . Oscillograms of pulses extracted from the cable after the first, third, seventh, and seventeenth passages through the cable corresponding to delay of the pulse by 0. 5, 1. 5, 3. 5, and 8. 5 mu sec, are shown.
