AB - We developed a fast kicker magnet for the Rare-RI Ring at the RI Beam Factory (RIBF) in RIKEN. The Rare-RI Ring is a storage ring developed to measure masses of unstable nuclei with a precision in the order of 10⁻⁶ *. The unstable nuclei are randomly produced in secondary beams by nuclear reactions of a DC primary beam from the RIBF accelerator complex, and their yields are as small as 1 event/day. Therefore, we apply the individual injection method to perform mass measurements of rare RI efficiently **. The developed kicker magnet is distributed constant type. The shape of magnetic ﬁeld is essential to the individual injection, and the timing property is given by the inductance and capacitance components of the kicker. Based on results of simulations conducted for the equivalent electronic circuit, we optimized the electrodes and ferrite cores of the kicker. In June, we carried out the first commissioning of Rare-RI Ring using a 78Kr³⁶⁺ beam with an energy of 167 MeV/nucleon. We succeeded in injecting and extracting particle-by-particle by using the kicker system. In this contribution, we will report details of the kicker magnet and will show the performance evidenced at the commissioning.
