AI Technical Summary
Traditional cryogenic Dewar devices cannot effectively reduce external interference signals in harsh experimental environments, leading to distorted experimental data. Furthermore, their large size makes them unsuitable for installation in the central hole of a water-cooled magnet.
The device employs liquid nitrogen and liquid helium chambers for cooling, combined with a vacuum chamber to reduce the transmission of low temperatures, and uses superconducting coils and resistive coils to reduce interference signals. The cryo-mechanical components are eliminated to reduce the size of the device.
This improved the accuracy of experimental data, reduced external interference signals and vibrations, and met the installation requirements of the center hole of the water-cooled magnet.
