Abstract

The invention relates to the technical field of design methods for a magnetic focusing structure of a medical electrified particle synchrotron, in particular to a heavy ion or proton synchrotron with a medical 45-degree deflection magnetic focusing structure. The synchrotron comprises eight deflection dipole magnets and eight synchrotron linear sections, wherein the eight deflection dipole magnets and the eight synchrotron linear sections are alternatively connected in turn through an annular vacuum pipeline; the eight deflection dipole magnet is 45-degree deflection dipole magnet; and the 45-degree deflection magnetic focusing structure comprises the annular vacuum pipeline in which electrified particles run and a magnet element, an acceleration element and an injection and extraction element which are arranged on the annular pipeline. The synchrotron has the advantages of effectively utilizing the space of the synchrotron, realizing the function of the medical heavy ion / proton synchrotron by arranging as few elements as possible, reducing manufacturing cost and installation space to the maximum extent, improving therapeutic efficiency and lowering treatment cost.

Description

technical field [0001] The invention relates to the technical field of a design method for a magnetic focusing structure of a medical charged particle synchrotron, in particular to a heavy ion or proton synchrotron with a medical 45° deflection magnetic focusing structure. Background technique [0002] A synchrotron is a device in which charged particles move circularly along a circular orbit to achieve accumulation and acceleration. It is widely used in nuclear physics, atomic physics experimental research, radiation materials, tumor treatment and other applied research fields. The electric and magnetic fields generated by electromagnetic elements such as dipole magnets, quadrupole magnets, and hexapole magnets arranged on the circular track constrain and guide the movement of charged particle beams, so that the beams have different sizes at different positions of the synchrotron. The beam sizes at each point on the orbit are connected in turn to form the beam envelope diag...
