	A 100 MeV H⁻ compact cyclotron (CYCIAE-100) has started operation from 2016 at China Institute of Atomic Energy (CIAE). The continuous proton beams of 75 MeV - 100 MeV has been extracted in dual opposite directions by charge exchange stripping devices. In order to analyze the extracted proton beam characteristics and control the beam loss for extracting 200 μA proton beam, the acceleration and stripping extraction process for the pulsed beam for CYCIAE-100 are simulated with the code of COMA in detail in this paper. The simulations are mainly done for the different RF acceptance or acceleration phase width. Due to the simulation results, the extraction turns are more for the large phase width and it will be reduced effectively with small phase width. The transverse beam distribution and the extracted beam profile are not affected by the initial phase width due to the simulation, that's the characters of the cyclotron with the stripping extraction mode.

	CYCIAE-230 superconducting cyclotron, a medical accelerator for proton therapy, is designing and constructing at CIAE now. An internal PIG source was adopted to attain a compact and simple design. Central region electric and magnetic field design will directly affect the beam quality and reliability of the cyclotron in terms of phase selection, beam loss and beam stability. Moreover, a favourable central region will ensure single-turn extraction efficiency. The central region study was based on detailed orbit tracking results, including the beam behaviour in the push-pull RF mode and phase selection and axial focusing in the latest magnetic field and electrical field distribution from calculation. The physical design results of central region beam dynamics are presented here.

CYCIAE-230 superconducting cyclotron, a medical accelerator for proton therapy, is designing and constructing at CIAE now. An internal PIG source was adopted to attain a compact and simple design. Central region electric and magnetic field design will directly affect the beam quality and reliability of the cyclotron in terms of phase selection, beam loss and beam stability. Moreover, a favourable central region will ensure single-turn extraction efficiency. The central region study was based on detailed orbit tracking results, including the beam behaviour in the push-pull RF mode and phase selection and axial focusing in the latest magnetic field and electrical field distribution from calculation. The physical design results of central region beam dynamics are presented here.
