SQUID Readout Electronics and Magnetometric Systems for Practical Applications

Description

The working principles and phenomena the SQUID technology is based on are not so easy to understand by those, who want to use the technology for specific applications. This book builds a bridge for scientists and engineers to fill potential know-how gaps for all working together on SQUID systems and their practical applications. Key words like readout electronics, flux quantization, Josephson effects or noise contributions will be no obstacle for the design and use of simple and robust SQUID systems.
