Abstract :
The paper presents results, experiment and simulation, of quench/recovery study of coated YBCO "composite" test samples, cooled by boiling liquid nitrogen and subjected to an over-current pulse. To operate stably and be protected from damage under adverse operating conditions of a real device, the YBCO tape must be a "composite", loaded with normal metal of a sufficient thickness that significantly increases the thickness of the original YBCO tape.
