Determination and evaluation of the critical liquid nitrogen for superconducting levitator based on a novel temperature-weight coupling measurement device

Peng Pang, Jun Zheng, Chenling Xian

Liquid nitrogen (LN2) is the only cooling medium for the high-temperature superconducting (HTS) bulks in the superconducting levitator, which is the heart of the maglev train, to r…
