Pulse propagation on a superconductive neuristor

Both analytic study and experimental investigations on an electronic analog are presented which indicate the unstable nature of Parmentier’s traveling‐wave pulse on a superconductive neuristor. In the vicinity of a critical bias level, the pulse is almost stable in the sense that pulse distortion over a finite distance can be made arbitrarily small by adjusting the bias to be sufficiently close to the critical value. It is also shown that the strength‐duration curve for threshold excitation can be obtained by equating input magnetic flux to that of Parmentier’s pulse. Finally an R‐T junction has been realized by resistive coupling of two neuristor lines and used to introduce a circulating pulse onto a storage ring.
