After successful completion of the course, students are able to describe the physical fundamentals of the operation of SQUID sensors in the context of the available sensor types. They know the requirements for a successful application of SQUID sensors in experiments. After successful attendance of the course students will be able to reasonably devise or debug their own experimental setups based on SQUID sensors.
Short introduction to the necessary basic concepts in superconductivity: flux quantization, Josephson equations, tunnel junctions Description of the concepts behind SQUID sensors Applications based on SQUID sensors (devices and experimental setups) other devices based on Josephson effects: Volt standard, digital devices
During the lecture the path from theoretical ideas to the construction and application of SQUID sensors is described. The lectures are complemented by short repetitions and discussion of the previous section with the students. The possibilities for use are discussed in terms of the limiting influences (internal noise, external vibration, external electromagnetic noise) and illustrated by anumber of exemplary use cases.
