Summary

The paper describes the structure of a nitrogen cryostat with a narrow tail used for electromagnetic measurements, and the experimental and theoretical results of its characteristic thermodynamic parameters. An analytical method is depicted to provide theoretical guidance for designing this sort of cryostat so as to obtain as low a working temperature as possible. According to the experimental data and theoretical calculations, lowering the surface pressure of solid nitrogen leads to the lowest working temperature of the nitrogen cryostat with a narrow tail, which is about 45 K.
