Specific fabrication techniques of the Polo model coil and its components

Poloidal field coils of Tokamak machines are characterized by their pulsed operation needed for plasma ramp up and control. They have to sustain operation faults such as plasma disruptions in their superconducting state. A low-loss conductor, low-loss structural reinforcement and a high-voltage insulation system are needed for fulfilling these requirements. The basis for this technology has been developed for a superconducting model coil. The fabrication technique applied for the coil and some high-voltage related components are described.< >
