Description
In the fourth-generation light sources, storage ring lattices are typically compact, potentially leading to serious cross-talk effects. Reducing the leakage field of a magnet offers an effective solution. In this paper, a novel permanent dipole magnet structure is proposed to address the magnetic flux leakage in conventional designs. Compared to traditional steel sheet shielding, this structure demonstrates superior performance in reducing leakage fields. Based on this structure, a protective permanent dipole magnet for the front end of a beamline of the Hefei Advanced Light Facility is developed and simulated using the 3D finite element method. The dipole achieves a peak field of 1.49 T with a leakage field significantly reduced to under 10 Gauss at 30 mm. This work offers a viable method to developing future permanent magnets with low magnetic cross-talk.
