The objective of this article is to apply the regenerative extraction system to a 250MeV proton superconducting synchrocyclotron. The parameters of the regenerative extraction system are determined by iteratively calculating the appropriate magnetic field and particle trajectory in the region where the magnetic field and particle trajectories interact. This is then combined with the magnetic channel system to achieve the extraction of the beam from the accelerator. In the article, the particle orbit dynamics analysis and the design of relevant parameters for the regenerative extraction system were successfully implemented using Matlab programming. The simulation results showed that the stability in the vertical direction has the greatest impact on the extraction efficiency and determination of the regenerative magnetic field parameters. In order to maximize the particle extraction efficiency, the radial displacement of particles in the last few turns should pass through two identical nodes.
