  The beam commissioning of J-PARC linac has been started in November 2006. In the beam commissioning, the tuning of the RF phase and amplitude for its DTL (Drift Tube Linac) has been performed with a phase-scan method. Detailed results of the RF tuning are presented with a brief discription of the tuning procedure.

  In the beam commissioning of J-PARC Linac, RF phase and amplitude of SDTL (Separate-type Drift Tube Linac) cavities have been tuned with a phase-scan method based on the beam-energy measurement. The output beam energy is measured with two FCTs (Fast Current Transformer) using the TOF (Time-Of-Flight) method. The detailed results of RF tuning for SDTL cavity is presented.

  The beam commissioning of J-PARC linac has been started in November 2006. Beam Position Monitors (BPMs) which have been calibrated on the bench setup with a scanning wire, utilize beam based calibration to relate the BPM center and the center of Q magnet. In this presentation, detail of installed BPM and the calibration methods are described.
