Abstract :
Examines dielectric breakdown phenomena under some environments peculiar to superconducting coils, such as an internal high voltage and thermal bubbles in the coolant generated by the coil quench, as well as high magnetic field and low temperature. Breakdown mechanisms of vacuum, gaseous helium, and liquefied gas are also discussed
