TI - Eddy Current Effects on the Stored Beam Generated by the Pulsed Sextupole Magnet at KEK-PF J2 - Proc. of IPAC2021, Campinas, SP, Brazil, 24-28 May 2021 CY - Campinas, SP, Brazil T2 - International Particle Accelerator Conference T3 - 12 LA - english AB - The Photon Factory (KEK-PF) has been continuously developing new technologies for the top-up injection using the pulsed multipole magnets (PMM). We demonstrated beam injection with the PMM successfully at KEK-PF and operated for synchrotron user experiments with top-up injection in four years. One of the important issues to be solved in this injection is the effect of eddy currents on the stored beam generated in the PMM and its inner coating of the ceramic duct. The magnetic field of the PMM is designed so that it does not affect the stored beam, however, the eddy currents that occurred on the coating give an unwanted kick to the stored beam at the injection. In this paper, we report eddy current effects on the stored beam generated by the pulsed sextupole magnet. PB - JACoW Publishing CP - Geneva, Switzerland ER -
