The Applied Superconductivity Laboratory, Physics Department, was established in 1992 for research of the properties of high-temperature superconductors (HTSC) and development of HTSC electric devices. The basic directions of the research activity are:


Series of the experimental models of the electric power and electronic HTSC devices have been and successfully tested. The 1000V/25A prototype of an inductive fault current limiter was tested in 1994. Fast operating controlled and non-controlled electronic switches based on HTSC thin film were developed and tested at ELTA Electronics Industries Ltd. Several original methods for measurements and theoretical analysis of the electromagnetic properties of superconductors like AC losses, critical current, shielding properties, flux creep and flow, development and propagation of the normal zones, were developed.
The laboratory activity was supported by more than 10 research grants from the Israeli Ministry of Science (1992-95 and 1994-96); Ministry of Infrastructure of Israel (2000-2003 and 2001-2004), Ministries of Science of Israel and Hungary (joint Israeli-Hungary researcher exchange programs) (1996-1998 and 1999-2000); G.I.F. (Germany-Israeli Foundation for Scientific Research & Development) (1997-1999); National Israeli Science Foundation (National Academy of Israel) (1997-2000); BGU-VaTaT (1998, 2000, and 2001).
Results of the investigations are published in the journals: “IEEE Transactions on Magnetics”, “IEEE Transactions on Applied Superconductivity", "Physica C", "Applied Superconductivity", "Cryogenics" and in the Proceedings of International Conferences (see list of publications). The members of the group actively participate in organization and work of Summer Schools and workshops with participation of the industrial representatives.
