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.
