A superconducting cyclotron based on proton therapy facility is being developed at Huazhong university of science and technology (HUST). Due to the compact size of the main magnet, the beam orbits at the extraction region are distributed densely, which creates difficulties for beam extraction leading to severe beam loss. In order to deal with these challenges, the orbit precession method has been employed in the extraction system design. In this paper, we introduce a method of employing a first harmonic field near the nu_r=1 resonance where the beam energy is about 248 MeV to adjust the amplitude of beam orbit oscillation. The optimum amplitude and phase of the first harmonic field are designed to obtain a large turn separation in the extraction region. Three different ways of generating the first harmonic field are compared for optimization.

	Utilizing dedicated cyclotrons to produce medical isotopes is an arising technology in hospitals across Canada. Thus, in January 2015, the CycloMed99 team, led by TRIUMF, demonstrated a breakthrough in producing the world’s most highly used medical isotope, technetium-99m (Tc-99m), on existing medical cyclotrons. Now we propose to design an innovative superconducting cyclotron for production of commercially valuable radioisotopes. This project will be focusing on a proton energy of 70-150 MeV and proton current of 2 mA. In this energy range, numerous increasingly demanded radioÂnuclides can be produced, either as parent nuclei for generator use, or directly as a active pharmaceutical ingredient, e.g. Strontium-82 (Sr-82), Actinium-235 (Ac-235) and Bismuth-213 (Bi-213). Our machine shall be designed to accelerate H²⁺, by injection from external ion source and extraction by stripping. This shall allow to simultaneously extract multiple cw proton beams of variable currents and potentially variable energies to multiple experimental stations with extremely high extraction efficiency. The basic parameters of the machine and the simulations of stripping extraction will be presented.
