AI Technical Summary
Traditional cryogenic Dewar devices cannot meet the cryogenic requirements for superconducting coils to enter the superconducting state under harsh experimental conditions, resulting in distorted scientific experimental data.
Design a long-tailed Dewar device, comprising a Dewar shell, a cryogenic Dewar assembly, and a sample rod assembly. The sample rod sleeve is cooled by liquid nitrogen and liquid helium chambers, and cryogenic leakage is reduced by vacuum chamber and guide tube, ensuring the cooling accuracy of the sample end.
Precise cooling of superconducting coils was achieved in harsh environments, meeting the low-temperature requirements of the superconducting state and reducing the impact of the external environment on experimental data.
