Applied Superconductivity: theory, superconducting materials and applications-Didactic Material prof. Palmieri Enzo

Author: prof. Palmieri Enzo ; Type of thesis: Didactic Material
Abstract: When hearing about persistent currents recirculating for several years in a superconducting loop without any appreciable decay, one realizes that we are dealing with a phenomenon which in nature is the closest known to the perpetual motion. Zero resistivity and perfect diamagnetism in Mercury at 4.2 K, the breakthrough during 75 years of several hundreds of superconducting materials, the revolution of the “liquid Nitrogen superconductivity”; the discovery of still a binary compound becoming superconducting at 40 K and the subsequent re-exploration of the already known superconducting materials: Nature discloses drop by drop its intimate secrets and nobody can exclude that the last final surprise must still come.
After an overview of phenomenology and basic theory of superconductivity, the lectures for this academic training will focus on the evaluation of the different classes of superconducting materials and on some selected industrial application of superconductivity. Continue reading

Superconducting resonant cavities-Didactic Material prof. Palmieri Enzo

Author: prof. Palmieri Enzo ; Type of thesis: Didactic Material
Abstract: There is no dubt that the subject of superconducting resonant cavities is a fascinating field both physical and engineering point of view.
The application of superconductivity to the world of resonant cavities has made achievable results unimaginable otherwise.
Independently of the special field of application, superconducting resonant circuits have superior performances compared to roo-temperatire circuits.
However the greatest resource of such devices stays not in the high quality of the results already obtained, but in all potential applications and new ideas that must be still developed.

The classical superconductivity-Didactic Material Prof. Enzo Palmieri

Author: Prof. Enzo Palmieri ; Type of thesis: Didactic Material
Abstract: When hearing about persistent currents recirculating for several year in a superconducting loop without any appreciable decay, we realize that we are dealing with a phenomenon wich in nature is the closest we know to the perpetual motion.
The zero resistivity and the perfect diamagnetism in Mercury at 4.2 K, the discovery of superconducting materials, finally the revolution of the “liquid Nitrogen superconductivity”: Nature discloses drop by drop its intimate secrets.
Nobody can exclude that the final surpreise must still come.
