Axial injection beam line of the therapy cyclotron is presented. It is intended for transportation of the C⁵⁺ ion beam obtained in the permanent magnet ion source. The beam line is only 3.486 m from the ion source to the entrance of spiral inflector, it consists of two sets glasser lens, one set double 90° bend magnet, one quadrupole lens and two solenoid lens. A big vacuum chamber is installed in the vertical part of the beam line, the sinusoidal buncher, the Faraday cap, the slit collimator and chopper are located in the vacuum chamber. The sinusoidal buncher is used for increasing of the seizing efficiency. The Faraday cap is used for the beam diagnostics. The bend magnet with the slit collimator is used for choice of C⁵⁺ ion beam. The chopper is used for choice of the beam utilizing time.

The 7MeV/u cyclotron accelerates carbon ions with mass number 12, 5+ charges, the extraction energy of carbon ions is 7 MeV/u, and the beam current density is designed to be 10 eμA. It designed as injector for the HITFiL (Heavy Ions Therapy Facility in LanZhou) synchrotron, which accelerates carbon ions to the energy 300 MeV/u for tumors treatment. Computer modeling results on the axial injection, magnetic, accelerating and extraction systems of the cyclotron are given. Design of the main systems of the cyclotron and the results of beam dynamic simulations are introduced. The construction progress including the ECR ion source, the axial injection beam line, the magnet, the RF system, the vacuum system etc. will be described respectively.
