Abstract

Electrical insulation of superconducting magnets needs to endure a variety of voltages with a large range of shapes, magnitudes and duration under normal operation, during coil quenching, and at withstand voltage tests. The author reviews the current state of electrical insulation technology for superconducting magnets in Japan. He maintains that Japan will continue to aggressively pursue the research, development and application of superconducting magnets. In accordance with this, the main technical subjects to be solved in the insulation of the superconducting magnets in the near future will be: (1) the development of insulation that has high electrical, mechanical and radiation-resistant properties at the cryogenic condition; and (2) investigation into the long-range effects of insulation on the stability of superconducting magnets.<>
