Title:
STRUCTURE AND METHOD FOR EXCITATION ACROSS DEWAR WALL, AND MAGNETICALLY CONDUCTIVE MIDDLEWARE
Document Type and Number:
WIPO Patent Application WO/2024/078439
Kind Code:
A1
Abstract:
The present invention relates to the technical field of superconducting excitation, and in particular to a structure and method for excitation across a Dewar wall, and a magnetically conductive middleware. The structure for excitation across a Dewar wall comprises a flux pump, a superconducting stator, a magnetic yoke and a superconducting load. The flux pump is arranged outside a Dewar. The superconducting stator the superconducting load are connected to each other so as to form a closed loop, and are arranged in the Dewar along with the magnetic yoke. The magnetic yoke and the flux pump are closely adjacent to the same Dewar wall area, and the superconducting stator is located in an air gap between the magnetic yoke and the flux pump. The magnetically conductive middleware comprises a carrier and a magnetically conductive element embedded in the carrier, the carrier being made of a non-ferromagnetic material. The method for excitation across a Dewar wall comprises: generating an alternating traveling wave magnetic field by means of a flux pump arranged outside a Dewar; the alternating traveling wave magnetic field being transmitted into the Dewar; and exciting a superconducting stator by means of the alternating traveling wave magnetic field. In the present invention, the flux pump is arranged outside the cryogenic vacuum Dewar, such that the flux pump has more heat dissipation mode options, and the size limit of the flux pump can also be ameliorated.
