The KEK Laser ablation ion source (KEK-LAIS) has been developed in order to obtain highly ionized metal ions and fully ionized carbon ions since 2012. Recently, the electron cyclotron resonance ion source of the KEK-Distal accelerator (KEK-DA) , which is a small-scale induction synchrotron, has been replaced by the LEK-LAIS A 2 micro sec long fully ionized carbon ion beam with 10^8 ions, which was delivered from the LAIS mounted on the 200 kV high voltage platform, was directly injected into the KEK-DA ring at 0.5 Hz without an injector, as well as C5+ and C4+. They were captured by the barrier bucket to survive until beam intensity life. Beam parameters, such as intensity distribution and emittance in the low energy beam transport line, the momentum spread and beam lifetime in the ring, were measured. It is noted that the first step of the essential characteristics required for a carbon driver of future carbon therapies has been demonstrated.
