OSTI ID:6073867
This paper discusses the feasibility of using NbTi internally cooled cable superconductor (ICCS) in the ohmic-heating central solenoid for the fusion engineering device (FED). The ICCS conductor provides cryostable operation with liberal stability margin. The forced cooled concept has a high winding current density which reduces the size and the cost of the device. The forced-cooled concept requires complex helium manifolding, but a unique approach has been developed to solve the problem. The conductor design, the winding design, and the performance analyses are described. The solenoid is designed to operate at 8-T peak field and provides 60 MAT. The operating current for the solenoid is 21.3 kA, which is 60% of the critical current at 8 T.
