In 1932, the #cryogenic laboratory led by Lev Shubnikov was the first in the USSR to achieve helium liquefaction, a technological breakthrough that facilitated further research, culminating in the discovery of type II #superconductivity (named the Shubnikov phase) in 1936. These spherical containers were used for the storage of liquid hydrogen.
