Axial injection beam line of a compact cyclotron

Axial injection beam line of the compact 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 glasser lens, one double 90-degree bend magnet, one quadrupole and two solenoid lens. The sinusoidal buncher, Faraday cap and chopper are used respectively for increasing seizing efficiency, beam diagnostics and choice of beam utilizing time. The bend magnet and a slit collimator are used for choice of C5+ ion beam.
