At the Rapid Cycling Synchrotron (RCS) in Japan Proton Accelerator Research Complex (J-PARC), theoretical predictions have indicated that the kicker impedance would excite the beam instability. A 1-MW beam with large emittance can be delivered to the

The vacuum system in the rapid-cycling synchrotron of the Japan Proton Accelerator Research Complex has been operated for more than 10 years. It becomes evident that the high-power beam operation has more powerful effects on the vacuum system than ex

The present four-terminal kicker at the rapid cycling synchrotron (RCS) at the Japan Proton Accelerator Research Complex has the power-saving benefit that it allows beam extraction by doubling the excitation currents with two shorted ends. In this co

A new horizontal shift bump electromagnet for the J-PARC 3-GeV RCS injection bump system was designed and fabricated. The bump magnet is a pulse magnet that repeatedly excites a trapezoidal waveform of about 1.5 ms duration at 25 Hz. And it is possib
