Helium groove of compound superconducting solenoid magnet coil

Abstract

The invention relates to the technical field of a particle accelerator superconducting solenoid magnet, in particular to a helium groove of a compound superconducting solenoid magnet coil. The helium groove is characterized by comprising a superconducting solenoid magnet coil frame, wherein the superconducting solenoid magnet coil frame is packaged in the helium groove and comprises a beam passage tube, the beam passage tube serves as two pairs of horizontal and vertical runway-type coil frames, a main magnetic field coil frame sleeves the beam passage tube, two shielding magnetic field coil frames are arranged at the two ends of the main magnetic field coil frame, distances tubes are correspondingly arranged between the main magnetic field coil frame and the shielding magnetic field coil frames, helium groove end plates are arranged outside the shielding magnetic field coil frames, and a liquid helium outlet, a liquid helium inlet and a current lead interface are further arranged on the helium groove. The helium groove has the characteristics of compact structure, strong magnetic field and low stray field, is easy to manufacture and convenient to assemble, and is simple in positioning and low in welding workload and welding deformation, the processing accuracy is easily guaranteed, and the assembly accuracy can be effectively ensured to reach requirement.

Description

technical field [0001] The invention relates to the technical field of superconducting solenoid magnets for particle accelerators, in particular to a composite superconducting solenoid magnet coil helium tank. Background technique [0002] The accelerator-driven subcritical system (ADS) bombards target nuclei (such as lead, etc.) with high-energy and intense proton beams generated by the accelerator to generate spallation neutrons as external neutrons to drive and maintain the operation of the subcritical reactor, which has inherent safety. In 2011, the Chinese Academy of Sciences launched the "Future Advanced Nuclear Fission Energy" strategic pilot technology project, in which the ADS transmutation system is one of its two major deployment contents. [0003] ADS injector II composite superconducting solenoid is one of the most important components of the transmutation system. The composite superconducting solenoid is used to generate a strong magnetic field, and the anti-re...
