Simple Laboratory Methods for Obtaining of Subnitrogen Temperatures in the Region 77-50 K and 5-35 K

Abstract

The article describes laboratory techniques and cryostats design to obtain subnitrogen cryogenic temperatures in two steps: 1) from 77 to 50K by pumping vapors of liquid nitrogen or eutectic N2 - O2 mixture; and 2) by adiabatic hydrogen desorption.
