The single-pulse formation technique using a beam chopping system consisting of two types high-voltage kickers was improved to enhance the quality and intensity with pulse interval over 1 μs at Japan Atomic Energy Agency cyclotron facility. A contamination rate neighboring bunches in reduced less than 0.1%. Long-term purification single guaranteed by well-controlled magnetic field stabilization for magnet. Reduction multi-turn extraction number suppressing bunch achieved restriction phase width precise optimization particle acceleration phase. In addition, increased factor or more combination bunchers sinusoidal saw-tooth voltage waveforms. Provision high intense contributed improve accuracy experiments investigation scintillation light time-profile neutron energy measurement time-of-flight method.
