A superconducting synchrocyclotron beam dynamics method

Abstract

This invention provides a beam dynamics method for a superconducting synchrotron accelerator, relating to the field of proton cyclotron accelerator technology. The method includes: Step 1, reading the initial parameters of the program, including the size and number of nodes of the three-dimensional field, particle parameters, high-frequency voltage and initial phase, nonlinear variation parameters of the high-frequency frequency over time, and the total time step; Step 2, based on the initial parameters, reading magnetic field and electric field data, and storing the magnetic field and electric field data in the form of a four-dimensional array; updating the magnetic field and electric field data using harmonic field parameters, including initial radius, initial angle, numerical value, maximum radius, and maximum angle, to obtain updated field data. This invention improves the accuracy of particle motion simulation, reduces computational load, effectively assesses accelerator operating deviations, and reduces beam loss caused by phase slip by updating field data, interpolating field data, calculating particle parameters, determining particle state and phase slip, and terminating the program.
