Integrating Htsc Thin Films in an Optical-Cryogenic Gravimeter

This paper considers the problem of designing and developing optical-cryogenic devices using new materials. We have shown how to produce reliable YBCO thin films with controllable surfaces and physical properties and how to integrate them in a ring form into the optical-cryogenic gravimeter so as to reduce its size and render it convenient for future space applications. Its function is based on the magnetic levitation phenomenon of the probe and on the measurement of its displacement with subsequent data processing
