Description
Three Lambertson magnets are utilized in the injection and extraction of the High Energy Photon Source (HEPS) booster. These magnets incorporate an embedded spliced core structure, integrating structural components made from FeCoV alloy (1J22) with a core composed of DT4 material. The 1J22 components are longitudinally segmented according to the core's length, with each segment processed and annealed independently before being spliced together. The regions prone to leakage magnetic fields are primarily shielded by the 1J22. Furthermore, the septum plate of the low-energy injection Lambertson magnet has a thickness of 3.75 mm, while the septum plates of the two high-energy Lambertson magnets are each 3.25 mm thick. Additionally, the uniformity of the integral main magnetic field is maintained within ±0.05%, and the integral of the leakage field is under 0.1% of the integral of the main magnetic field. The performance of the magnets all meet the specified physical requirements. In this paper, a lot of key problems in the development of magnet such as magnetic field distribution, manufacture of 1J22 components, are introduced and thoroughly discussed.
