The additional glazer lens on axial injection of AVF cyclotron has been installed to expand the beam accectance of cyclotron. Additional buncher for the heavy ion injection like Xe beam which requires high voltage in comparison with proton case also has been installed. Extension of baffle slits on injection line of Ring Cyclotron also has been done to extend the flexibility of injection orbit. Modification of low energy beam transport (LEBT) from ion sources to AVF injection axis including the development of fast emittance monitors also has been carried. Each component works well.
