Abstract

The invention belongs to the application field of superconducting magnets and discloses a bit-like superconducting magnet based on a ReBCO coating conducting sheet. The bit-like superconducting magnet based on the ReBCO coating conducting sheet includes superconducting sheets, insulation sheets, superconducting lead sheets and a fixing device. The insulation sheets and the superconducting sheets are overlapped under a first superconducting lead sheet in sequence, the adjacent superconducting sheets are welded, a second superconducting lead sheet is welded under the last superconducting sheet and the last insulation sheet, flanges are added on the top and the bottom, a locating pull rod penetrates through a locating hole of each sheet to fix all sheets together and form a whole single bit-like superconducting magnet; or single bit-like superconducting magnets are nested mutually through the adjustment of the inner radius and the outer radius, so that multi-level bit-like superconducting magnets are nested into a combined superconducting magnet. The bit-like superconducting magnet not only can output a high magnetic field, but also be stable, compact in structure and capable of realizing multi-level nest conveniently and processing general insulation easily.

Description

technical field [0001] The invention belongs to the application field of superconducting magnets, and particularly proposes a bit-like superconducting magnet based on a ReBCO coated conductor sheet. Background technique [0002] Strong magnetic field is an important extreme condition for scientific research. Studying high magnetic field test devices with different magnetic field strengths provides different experimental approaches for the development of science and technology. With the rapid development of superconducting technology, both commercial development and experimental design require increasingly stronger magnetic field strengths to test various properties of materials. At present, no matter in the world or in China, the designed magnets can provide a magnetic field strength of less than 45T, and the cost is very high. According to the characteristics of Bitter-magnet and high-temperature superconducting ReBCO coated conductor, the two models are applied to the des...
