Abstract : The aim of the work reported was to construct a physical realization of a continuously distributed neuristor, using the properties of superconducting fibers. The superconductive neuristor was developed theoretically from the electrical dual of the 'thermistor line,' following the ideas of M.W. Green. An equivalent circuit analysis, based on Green's model, was accomplished and the necessary conditions for neuristor action are defined in terms of the superconductive phenomena. An experimental study of the propagation of the normal phase along a superconductive filament required the major portion of the effort. The theory of Cherry and Gittleman has been verified for thin film filaments, and certain pertinent extensions obtained. Investigations of the recovery processes have shown that the physical feasibility of the totally distributed neuristor depends on the thermal isolation of the active and passive parts of the structure and is not attainable; however, the operation of a semi-distributed neuristor has been demonstrated experimentally and verifies the basic concepts involved in the original model. The possible employment and subsequent impact of the semi-distributed structure on the logic-system philosophy remains to be evaluated. (Author)
