A PULSED DIVERTER AND GUIDE FIELD FOR THE SUPERCONDUCTING LEVITRON

摘要

The design of a pulsed diverter and guide field for the Superconducting Levitron is optimized so that a maximum area at the remote end of the guide field coil is bounded by magnetic flux lines which lie on useful flux surfaces in the Levitron. The guide field is compensated for the fringe field of the Levitron. Flux lines are followed using a numerical calcula¬tion. For torus currents corresponding to 300 kA in the floating ring, a guide solenoid current producing about 15 kG results in the above area being about 2 or 3 cm by 4 or 5 cm.
