A NEW SUPERCONDUCTING LEVITATED-MASS SYSTEM

Y. Fujii, Y. Miki, F. Shiota

Abstract

A new superconducting levitated-mass system is now being developed with the final target of replacing the kilogram in terms of the fundamental constants. Improving the stability of trajectory by means of introducing a superconducting linear bearing is the issue in question for the first stage of this development. The present status of the development, experimental results and further prospects are discussed.
