Summary: The superconducting magnet group at IHEP has been working on high field accelerator magnets since 2014 for the study of next-generation particle accelerators. They have successfully built and tested several superconducting dipole magnets with increasing main field strengths. The latest model, LPF1-U, achieved a main field of 12.47 T in two apertures using a combined coil configuration of Nb3Sn and NbTi superconductors.

Summary: Although high-temperature superconducting material has the potential for high magnetic field applications in future particle colliders, further development in magnet and conductor technology is needed. The study presented the successful development of a C2 magnet using CORC(R) wire, showing high dipole field capabilities and reliable performance. Test results highlighted the need for improving the performance of CORC(R) wires and developing early detection capabilities for flux-flow voltage onset locations.

Summary: To improve the control accuracy of particle accelerator electromagnets, this study models the magnetic hysteresis behavior and magnetic after effect, which have been overlooked in previous research. Experimental data on the gap magnetic field of an accelerator magnet under different excitation conditions were measured to support the modeling process. The study reveals the influence of the magnetic after effect on the magnetic hysteresis behavior, suggesting the need for a novel modeling technique in addition to conventional hysteresis models developed in the electric machine field.

Summary: Replacing solid geometries with superconducting rings in levitation brings two important advantages: comparable forces but greatly reduced mass, resulting in increased trap frequency, and the additional control provided by the flux trapped in the ring by in-field cooling. However, stability in lateral and rotational directions is not guaranteed for this idealized geometry. Discussions on the requirements for achieving stability in all degrees of freedom in simple superconducting structures are provided.

Summary: A new modeling method is proposed to simulate transient processes in 2D models of complex multi-physical magnet systems, including thermal diffusion and quench development. By simplifying the quench development along the direction of the transport current, the computational efficiency and accuracy are improved. Comparisons between simulations and experimental results for a self-protected, superconducting Nb-Ti dipole magnet show a very good agreement between the two.

Summary: In this study, a compact, low-power magnetorheological fluid clutch is developed, which can variably and reversibly alter the shear stress of the fluid by activating an array of electropermanent magnets. By selectively polarizing the magnets, the clutch achieves rapid response times and variable torque transmission, offering a low-power alternative to traditional clutch designs.
