Abstract: The structure of superconducting magnet coils without turn-to-turn insulation was analyzed, and the effects of total number of layers and the turns for each layer on the equivalent total resistance and charge-discharge process of the coils were tested. The experimental results show that the variation trend of the equivalent total resistance is completely different when the total layer number is odd or even, but the order of magnitude is several multiples of the contact resistance between adjacent turns. The charge-discharge process of coils is directly affected by the equivalent total resistance. If the total resistance is greater, the excitation time will be shorter, but the induced voltage will be also larger, and the Joule heat will be increased. Therefore, the appropriate choice of equivalent total resistance and no insulation filling material are particularly important for the design of non-insulated superconducting magnet coils.

Key words: non-insulation, superconducting magnet coil, adjacent turn-to-turn contact resistance, equivalent total resistance, charge-discharge
