New Type of Non-Metal Liquid Nitrogen Vessel for Levitation System

A new type of non-metal liquid nitrogen vessel for levitation system is presented in this letter. It possesses thin bottom in thickness of 5.5~6 mm and the ability to maintain liquid nitrogen for about 5 hours. Its most advantage is that no eddy current will be caused on the moving of it above permanent magnet guideway. It is significant for the HTS to be put into use in the future.
