Project description:Investigation of methods for design and manufacturing of superconducting magnet coils from high temperature superconducting tapes using an original conductor architecture and innovative cooling concept is in the core of the proposed project. Superconducting tapes, laid helicoidally on metallic tube with diameter between 3 and 8 mm, form the cable conductor that can be cooled by the flow of coolant (liquid nitrogen, He gas) through the tube. Thermal insulation of the coil wound from such conductor can be very simple from the low cost polyurethane foam without necessity of vacuum. Because the properties of superconductor depend on temperature, magnetic field and mechanical strain, optimization of the conductor architecture and of the manufacturing process requires extensive modelling aimed at solving mechanical, electromagnetic and mechanical problems. Essential properties of used materials will be determined by experiments employing specialized measurement techniques and structural investigation methods. Higher level of problem complexity is expected in the design and manufacturing of a coil utilizing the optimally designed conductor. Final test of the proposed concept will be carried out on the coil of 120 mm inner diameter hosting in 4 layers 80 turns of conductor able to carry at least 1000 A when cooled by a liquid nitrogen flow, with thermal insulation less than 20 mm thick.
