Recent progress in the KEK induction synchrotron is presented. A single proton bunch, which was injected from the 500 MeV Booster ring and captured by the barrier bucket created by the induction step-voltages, was successfully accelerated to 6 GeV in the KEK proton synchrotron, by using a newly developed induction acceleration system instead of RF devices.
