Description

The beam commissioning of the J-PARC RCS was started in October 2007 and acceleration of 1.07 x 1013 protons has been successfully achieved in February 2008. Also, the beam commissioning of MR began in May 2008. The RF capture of the beam and the extraction at the injection energy of 3 GeV was successfully performed. In both of the RCS and MR, magnetic alloy (MA) cavities are employed to achieve high accelerating voltages which are necessary to accelerate the high intensity proton beams. We employ full-digital LLRF control systems to realize precise and reproducible control of RF frequencies, voltages and phases. We present the status of the RF acceleration with examples of the beam signals. Also we discuss the future plans. (author)
