J-PARCにおける3GeV RCSキッカ電磁石の実機が完成し、真空環境下において60kV, 25ppsでの磁場測定を行った。磁場の安定性、及び、同型キッカ電磁石の比較をし、議論を行う。

Production of the extraction kicker magnet of 3GeV RCS in J-PARC has been completed. We performed the magnetic field measurement in vacuum at the actual operation condition, which means the charging voltage of 60 kV and repetition rate of 25 Hz. We especially discuss the stability of the magnetic field and the comparison of the magnetic field between the same type of magnets.
