Stability and Vibrations of Internal Windings of High-Current Superconducting Solenoid Magnets

摘要: Abstract : High field solenoid magnets may experience internal damage or eventually collapse due to the powerful magnetic fields they produce. Elastic deformations of conductor and insulation in these deserve attention because can cause local that lead electrical breakdown. In conventional stress analysis cylindrically wound magnets, gradient, stiffness, is usually neglected. However, this thesis stiffness shown have a significant effect on elastic stability vibration magnets. One-turn multi-turn superconducting rings were used study effects vibration. Both static dynamic methods determine critical buckling currents. The dispersion natural frequencies with increase current subsequent in-plane out-of-plane near observed. A model based ring theory was developed explain experimental observations showed fair good agreement between theoretical values current. This evaluate 7- 10-turn concentrated outer turns. (Author)
