Description

Technical Field

[0001] The utility model relates to the field of scanning magnets, in particular to an integrated charged particle beam scanning magnet module. Background Art

[0002] Precise control and scanning of charged particle beams are crucial in modern scientific research and particle medicine. Charged particle beams are widely used in nuclear physics research, materials analysis, and particle medicine. When a charged particle beam passes through the magnetic field of a scanning magnet, it is deflected by the Lorentz force. Precise control of the magnetic flux density of the scanning magnet allows precise control of the beam's trajectory.

[0003] For example, particle beam spot scanning technology used in proton and heavy ion cancer therapy requires two scanning magnets, X and Y. Traditional scanning magnets are typically installed in a distributed manner, with the magnet body, control module, power module, mounting bracket, and other modules installed separately and connected by cables.

[0004] Traditional scanning magnet systems are bulky and heavy, difficult to transport and assemble, and require lengthy on-site installation and commissioning cycles. With technological advancements, the demand for miniaturized and integrated scanning magnets in fields such as accelerator nuclear physics research and particle therapy is increasing, and traditional scanning magnet systems are no longer able to meet these requirements.
