Scale Model-Driven Engineering Validation of Discrete Coil Technology (DCT) for CEE Superconducting Dipole

Résumé fourni par la source

The CSR External-target Experiment (CEE) is a large-scale spectrometer under construction at Lanzhou's Heavy Ion Research Facility (HIRFL), focusing on studying nuclear matter's phase structure (high baryon density) and equation of state (supra-saturation densities). Its key component is a large-acceptance dipole magnet: 0.5 T central field, 5% homogeneity within a 1m×1.2 m×0.9 m aperture (for detectors). An innovative superconducting magnet design is proposed: coil-dominant type with racetrack-shaped discrete conductors, plus a warm iron yoke (enhances central field, reduces stray field). The magnet is 3.4 m long, 2.7 m high, 4.3 m wide. Coils use 19-strand cables, supported by keels to withstand electromagnetic force. Due to its novel structure, the magnet scheme poses great technical challenges. Therefore, a 1/6-scale prototype magnet was developed to comprehensively verify the scheme's feasibility via the scaled-down prototype. This paper will detail the development process of this scaled-down magnet prototype.
