Title:
GAS-COOLED CURRENT LEAD AND SUPERCONDUCTING MAGNET SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/134265
Kind Code:
A1
Abstract:
A gas-cooled current lead and superconducting magnet system. The system comprises: a 4K container filled with liquid helium and a superconducting coil, a heater for heating the liquid helium, a cold head apparatus having a cooling function, a current lead, and a control apparatus, wherein an upper end of the current lead can be connected to a positive connector electrode and a negative connector electrode of an external power source by means of excitation cables, and a lower end of the current lead can be respectively connected to a positive connector electrode and a negative connector electrode of the superconducting coil by means of 4K inner cables; the heater, the cold head apparatus and the external power source are all connected to the control apparatus; the current lead has a tubular structure, and the top thereof is provided with a vent tube for venting helium; the current lead and the cold head apparatus are fixed in the 4K container by means of the same metal flange; an insulation member is sandwiched between the current lead and the metal flange; and a high-temperature superconducting tape is attached in the tubular structure of the current lead located below the metal flange. The apparatus can reduce the heat leakage of a current lead during steady-state operation of a magnet, and simplify an excitation operation.
