To analyze the H⁰ and the accelerated H⁻ particles, the bump magnet system was designed and produced. The H⁰ beam diagnostic line consists of four horizontal bending magnets, non-destructive beam position monitor and wire scan beam profile monitor. In the 2015 summer maintenance period of the J-PARC, the new diagnostic line was constructed in the beam transport (MEBT2), which is the matching section from separated-type drift tube linac (SDTL) to annular-ring coupled structure linac (ACS). In the beam commissioning, we experimentally confirmed that the accelerated 190 MeV H⁻ beams are horizontally shifted as expected with the magnetostatic field simulation and the particle tracking simulation.
