Abstract

The invention discloses a high-field superconducting magnet system with wide separation gaps. Superconducting coils of the system comprise a low-temperature superconducting coil (16) and a high-temperature superconducting coil (17). The superconducting coils are connected with a cold shield (3) and a flange (2) of a low-temperature container through a support pull rod (8), and are supported in the low-temperature container integrally. A thermoswitch (7) is connected with a primary cold head and a secondary cold head of a refrigerating machine (1), and the secondary cold head is connected with magnet-reinforcing support flanges (10) arranged at two ends of the low-temperature and high-temperature superconducting coils through a cold-guiding belt (5). The superconducting magnet system is provided with a horizontal room-temperature hole (12) and a vertical room-temperature hole (15); an outer cold shield (11) of the horizontal room-temperature hole is used for preventing heat radiation of the horizontal room-temperature hole (12) to the superconducting coils. A separation support frame (9) separates the low-temperature superconducting coil (16) and the high-temperature superconducting coil (17) into two parts, so when the superconducting magnets are integrated into a whole, a two-dimensional room-temperature space is contained in the integrated superconducting magnets.

Description

technical field [0001] The invention relates to a high magnetic field superconducting magnet system, in particular to a high magnetic field superconducting magnet system with a large separation gap. Background technique [0002] With the development of refrigeration technology and superconducting technology, high-field conduction-cooled superconducting magnets have a simple low-temperature system structure and are not limited by liquid helium or other low-temperature conditions. The system is easy to operate, and has the characteristics of compact structure and light weight. The key technology of the conduction cooling superconducting magnet system is to use a refrigerator to directly cool the superconducting magnet, which breaks the traditional cooling method that the superconducting magnet must be cooled by cryogenic liquid. With the development of high-temperature superconducting wire technology, the current density of Bi-based strips has J in the temperature range of 20-...
