Abstract :
To develop the high performance HTS coil operated in persistent-current mode, loss mechanisms of the HTS coil have been studied. We consider that the loss generation is associated with the shielding current and its temporal variations. To investigate the shielding current characteristics, the decay of shielding currents were measured under various conditions, and we evaluated these effects in simple experiments.
