Abstract: The present application provides a method for obtaining strong focusing of an isochronous accelerator by varying the magnetic field gradient in a large radial range. The method is characterized by the main magnet of the isochronous accelerator providing not only a bending effect but also a focusing effect, equivalent to the effects of quadrupole, sextupole, and octupole magnets used in a synchrotron accelerator.

Abstract: The invention discloses a method for adjusting particle orbit alignment by using a first harmonic in a cyclotron, including the following steps: generating a correcting magnetic field through eight coils symmetrically about the middle plane; arranging the positions of the coils and the currents applied, so that they can generate a first harmonic of which the amplitude and phase are arbitrarily adjustable; according to the actual eccentricity of the particle orbit, adjusting the magnitude and direction of the currents applied to the coils, and optimizing the alignment of the particle trajectory. By controlling an external DC power source of the accelerator and combining the real-time feedback of the beam detection of the accelerator, the invention may perform real-time adjustment during the debugging and operation of the accelerator, with high feasibility and operability; compared with traditional methods, the invention may achieve real-time adjustment during the debugging and operation of the accelerator.

Abstract: The present disclosure relates to a magnet pole for an isochronous sector-focused cyclotron having hill and valley sectors alternatively distributed around a central axis, Z, each hill sector having an upper surface bounded by four edges: an upper peripheral edge, an upper central edge, a first and a second upper lateral edges. The upper surface of at least one hill sector may further include: a recess extending over a length between a proximal end and a distal end along a longitudinal axis intersecting the upper peripheral edge and the upper central edge. The recess may be separate from the first and second upper lateral edges over at least 80% of its length, and a pole insert having a geometry fitting in the recess may be positioned in, and reversibly coupled to the recess.

Abstract: The accelerator includes a circular vacuum container which contains a circular return yoke. With respect to the central axis of the vacuum container, an incidence electrode is arranged towards the entrance of a beam emission path inside of the return yoke. Inside of the return yoke, electrodes are arranged radially from the incidence electrode in the periphery of the incidence electrode. Recesses are arranged alternately with the electrodes in the circumferential direction of the return yoke. In the vacuum container, an orbit-concentric region is formed in which multiple beam orbits centered on the incidence electrode are present, and, in the periphery of said region, an orbit-eccentric area is formed in which multiple beam orbits eccentric to the incidence electrode are present. In the orbit-eccentric region, the beam orbits between the incidence electrode and the entrance to the beam emission path are denser.
