1. A superconducting electromagnet component of an isochronous cyclotron, comprising:
a superconducting main coil disposed around a central axis, wherein the superconducting main coil comprises an upper main coil and a lower main coil, and there is a median plane between the upper main coil and the lower main coil;
a superconducting trim coil group disposed in the superconducting main coil around the central axis, wherein the superconducting trim coil group comprises an upper trim coil group and a lower trim coil group, and the median plane is located between the upper trim coil group and the lower trim coil group; and
a superconducting focusing coil group disposed on a side of the superconducting trim coil group away from the median plane, wherein the superconducting focusing coil group comprises an upper focusing coil group and a lower focusing coil group, and the median plane is located between the upper focusing coil group and the lower focusing coil group, wherein the upper focusing coil group and the lower focusing coil group each include:
a plurality of first focusing coils each having a first fan-shaped structure and disposed side by side around the central axis, wherein current directions of two adjacent first focusing coils are opposite; and
a plurality of second focusing coils each having a second fan-shaped structure and correspondingly disposed in the plurality of first focusing coils, wherein current directions of two adjacent second focusing coils are opposite.
