Voltage Noise Measurement of a REBCO Superconducting Coil During Electromagnetic Vibration Tests on a Ground Coil

Abstract

In electromagnetic vibration tests, a ground coil is excited under the strong magnetic field of a super conducting magnet. Since the vibration mechanisms in the test are the same as for actual maglev (magnetic levitation) running conditions, electromagnetic vibration tests are therefore an important durability test for ground coils. We carried out electromagnetic vibration tests with a superconducting magnet with REBCO wire, which is a high-temperature material. This paper also proposes a novel monitoring and protection method for REBCO magnets. this research and describes some examples of the practical application of the newly developed reinforcement method.
