Abstract : The direction towards which research and development in superconducting systems is going is reviewed. Nb-Ti alloys are found to dominate development of superconducting cables. The nature of field penetration in nonideal superconductors is shown to present a vexing problem. The actual design and construction of large scale superconducting systems is shown to be in its infancy. The concept of a magnetic pump for generating high currents in superconductors is emphasized. A detailed account is then given of the research going on in the High Temperature Institute. These include special flux linkage solenoid windings and an investigation in the induction of these superconducting solenoids. The detailed characteristics of three 65BY alloy superconducting solenoids are listed with solenoid constants of 0.78, 2.25, and 0.71 kilo-oersteds/amp. A figure compares the experimental and theoretical flux linkage curves of the three solenoids as a function of the nondimensional excitation current. Careful measurements are made of the static and dynamic inductance of each solenoid. The results show the connection between the inductance and the current during the first excitation, without prior history; the relationship between the inductance and the current during the solenoid discharge.
