BEAM DIAGNOSTICS AT THE FIRST BEAM COMMISSIONING OF THE J-PARC MR

J-PARC MR was successfully commissioned with single bunch accumulation and the beam intensity of typically 4x10 protons per bunch, 1% of the design value. Beam diagnostic devices: current monitor's (DCCT, FCT, WCM), BPM's, BLM's, profile monitors (SEEM, luminescence screens, FWPM, IPM) and tune meter have come into operation. Using outputs from these devices, beam related physical quantities were obtained with enough precision.
