Learning outcomes of the course :
|
| At the end of the course, students will be able to:
- demonstrate a knowledge and understanding of the electrical and magnetic properties of superconductors and their main difference with normal conductors;
- understand how to apply the basic theories of superconductivity to the analysis of their physical properties;
- understand the influence of the material microstructure on their current carrying abilities;
- demonstrate practical skills as well as the ability to carry out successful measurements in superconductors in cryogenic environment;
- show how the unique properties of superconductors can be exploited in various engineering applications.

Prerequisites and co-requisites/ Recommended optional programme components :
|
| The "Electromagnetism" course (ELEN-0076-1) should be attended the same year (if not, previously). |
|
Planned learning activities and teaching methods :
|
| Practical courses involve mandatory laboratory experiments (electrical resistivity, magnetic susceptibility, direct and indirect critical current measurements, levitation force), 3 lectures about the synthesis of high-temperature superconducting ceramics, scanning electron microscope (SEM) observations and a visit of the labs of the "SUPRATECS" research group ("Electronics instrumentation" section) |
