| Aim: "Superconductivity" aims at providing the students with a knowledge of superconductivity to such an extend that they have the necessary background for following the present and future applications of superconductors. Examples of such applications are power cables, coils, motors, generators, as well as measurement of very small magnetic fields (SQUID-magnetometers for biomagnetism, geology etc.), detection and processing of high frequency signals (integrated cryogenic microwave circuits for astronomy, communication etc.), and construction of extremely fast circuits (superconducting transmission lines and shift registres in digital computers). |
| Contents: Phenomenological description of superconductivity, electrical and magnetic properties, type I and type II superconductors, vortex dynamics, electron pair formation (Cooper pairs), electrodynamics of superconductors, superconducting cavities and transmission lines, tunneling, Josephson effect, circuit application, equivalent circuit of the Josephson element, dc and rf effects, fluctuations (noise) in Josephson elements, phase coherence of the macroscopic wave function, SQUID-magnetometers, and logic circuits. Visit to the laboratory facility for the production of superconducting thin film circuits with Josephson tunnel diodes. |
