	We had mainly carried on the debugging and commissioning of CYCIAE-100 for Beijing Radioactive Ion-beam Facility (BRIF) in 2016. The installation and commissioning of south extraction system in the remaining works, the south proton beam lines and part of experimental target stations had been completed, meanwhile, the installation of partial shields for the fort section also had been finished in the large experimental hall, and they had been put into physical experiment for the first time. The debugging work of CYCIAE-100 went well, the maximum internal target beam was 1073uA, and the maximum external target beam had reached 45uA. It ws the first time that the CYCIAE-100 had provided proton beam 500 hours in 2016 for the physics experiment of single event effect, measurement of proton effective dose, white light neutron, and proton radiography.

	Proton Therapy is a high accuracy cancer treatment way with little side effects and widely investigated in recent years. Introducing superconducting technologies, China Institute of Atomic Energy has designed a cyclotron to extract 230 MeV proton for cancer therapy. Extracted beam loss is one of the very crucial parameter in this machine. A low beam loss has benefit in reducing the dose level inside the cyclotron and preventing device damage, and consequently keeps the machine operate stable in long time. Two electrostatic deflectors are installed in the adjacent magnet hills to deflect the beam for extraction. The Vr=1 resonance and precession motion are introduced in extraction region to enlarge the turn separation. After the deflectors, passive magnetic channels provide radial focusing force to restrain the beam dispersion in the edge field. In this paper, the design process and simulation results will be introduced in detail. Also, the extraction element layout will be illustrated.

Proton Therapy is a high accuracy cancer treatment way with little side effects and widely investigated in recent years. Introducing superconducting technologies, China Institute of Atomic Energy has designed a cyclotron to extract 230 MeV proton for cancer therapy. Extracted beam loss is one of the very crucial parameter in this machine. A low beam loss has benefit in reducing the dose level inside the cyclotron and preventing device damage, and consequently keeps the machine operate stable in long time. Two electrostatic deflectors are installed in the adjacent magnet hills to deflect the beam for extraction. The Vr=1 resonance and precession motion are introduced in extraction region to enlarge the turn separation. After the deflectors, passive magnetic channels provide radial focusing force to restrain the beam dispersion in the edge field. In this paper, the design process and simulation results will be introduced in detail. Also, the extraction element layout will be illustrated.
