| Abstract |
The development of a magnet for very high magnetic field is usually envisioned with the use of an HTS insert coil. Pancake windings have been commonly used for the insert coil. All pancake windings have been connected in series and excited by a single power source. In that case, it is inevitable to operate some of the pancake windings well below their critical current densities. To increase the central magnetic field of the magnet, this paper proposed a new excitation method of the pancake windings by exciting the pancakes windings independently using multiple power sources. Results of the calculation show proposed method increases the central magnetic field of the magnet which consisted of 8 pancake windings by 17% comparing with excitation by using a single power source. |
