Abstract :
A refinement of a preliminary superconducting magnetic levitation system is in progress for the determination of the magnetic flux quantum Phi /sub 0/. A novel superconducting coil with a conic section has been fabricated, so that the Meissner effect of the system seems to remain intact and the basic characteristic of the levitation system is much improved.<>
