Integrated superconducting detectors

The main focus of the project is the research into the properties of high-temperature oxide superconductors for detector applications for various different types of radiation from microwaves to cosmic rays. In the project the different processes leading to efficient detection of different types of radiation are investigated which may be used for different possible applications. A key element of the project is the development and characterization of laser patterning of oxide superconductors on different substrates down to 1 micron level for detector and microwave device applications. Microwave devices using the technology are fabricated and tested. The frequency, spectral and temperature response characterization of elementary superconducting detector devices using the Y-Ba-Cu-O superconductor is perfomed. Finally an important part of the project is the construction of a prototype autonomous detector system with an operating temperature of 80K using a portable Stirling engine cryocooler.
