In modern scientific research and industrial applications, precise control and scanning techniques of charged particle beams are of great importance. Charged particle beams are widely used in the fields of medical imaging, material analysis, particle accelerators, etc. Conventional scan magnets often face technical challenges such as the thin-walled vacuum box and scan magnet being separate, the overall volume being large, and there being some gap between the two components, the compactness being poor. When the thin-wall vacuum box is vacuumized, the outer wall of the chamber bears atmospheric pressure, the thin-wall vacuum box can be extruded and deformed to a certain extent, and the scanning precision is affected, so that the structure of the thin-wall vacuum box needs certain rigidity and strength. In order to ensure the rigidity and strength of the thin-wall vacuum box in the traditional scanning magnet, reinforcing ribs are often welded on the surface of the thin-wall vacuum box. The traditional scanning magnet is large in size and heavy in weight, and the use of the traditional scanning magnet in some application scenes is limited. How to solve these problems becomes important.

the thin-wall vacuum box is tightly attached to the saddle coil, the concentric winding iron core and the airtight filler, and a high self-adhesive material is coated between the thin-wall vacuum box and the saddle coil.
The further technical scheme is as follows: the airtight packing is made of a material having high strength and high temperature resistance.
The further technical scheme is as follows: the saddle coil is made of a high-conductivity material.
The further technical scheme is as follows: the concentric winding iron core is formed by winding a high-permeability material.
Compared with the prior art, the invention has the following beneficial technical effects:
(1) The airtight filler is arranged among the thin-wall vacuum box, the saddle coil and the concentric winding iron core, so that the gap between the thin-wall vacuum box and the scanning magnet is eliminated. So that the thin-wall vacuum box and the scanning magnet are integrated.
(2) The thin-wall vacuum box has weaker structural strength due to thinner wall thickness. Therefore, after the airtight filler is placed, no gap exists between the thin-wall vacuum box and the scanning magnet, and the high self-adhesive material is coated between the thin-wall vacuum box and the scanning magnet, so that the structure of the thin-wall vacuum box is reinforced; when the inner cavity of the thin-wall vacuum box reaches a certain vacuum degree, the outer wall of the thin-wall vacuum box is not directly subjected to atmospheric pressure, but is subjected to the integral structure of the scanning magnet, so that the thin-wall vacuum box is not easy to deform and fail; the scanning accuracy of the charged particle beam is ensured.
(3) The thin-wall vacuum box has no reinforcing ribs; the concentric winding iron core is made of high-permeability material, so that the material consumption is low; the iron core adopts a concentric winding process, is different from the traditional silicon steel sheet stacking process, and has no fastener; therefore, the scanning magnet has compact overall structure, small volume and light weight, and is convenient to install and use; the miniaturization and the light weight of the scanning magnet are realized.
