Abstract
The disclosure provides a hybrid magnet structure which includes two dipole magnets assemblies arranged oppositely, and each dipole magnet assembly includes a permanent magnet, two iron cores, and a moveable magnetic field shunt element. The hybrid magnet structure is adapted to focus particle beams of different positions by applying an adjustable gradient magnetic field in the horizontal or vertical direction of the particle beam. By passing the charged particle beams through the gradient magnetic field established between the two dipole magnets, the aspect of focusing the charged particle beam is achieved. In addition, the intensity of the gradient magnetic field can be altered by adjusting the gap between the movable magnetic field shunt element and the permanent magnet, thereby controlling the particle beam size on a specific axis for different energies or masses of the charge particles.
