Acceleration of High-Intensity Heavy-Ion Beams at RIKEN RI Beam Factory

Recent efforts concerning the RIBF accelerators in RIKEN have been directed towards achieving higher beam intensities of very heavy ions such as uranium and xenon. As presented in the last IPAC conference in 2013, the intensities of these ion beams have significantly improved due to the construction of a new injector, RILAC2, which is equipped with a 28-GHz superconducting ECR ion source, the development of a helium gas stripper, and upgrading of the bending power of the fRC. In this light, this paper presents the subsequent upgrade programs carried out in the last couple of years, such as developments of a new air stripperforxenonbeamsanda micro-ovenfor metallic ions. The currentperformancelevel ofthe RIBF acceleratorcomplex, as well as a future plan to further increase the beam intensities, are also presented.
