  Recent efforts at the RIKEN RI Beam Factory (RIBF) are aimed at increasing the beam intensity for very heavy ions such as xenon and uranium. This paper presents upgrade programs carried out over the past few years, including modifications of the RF cavities of the RIKEN Ring Cyclotron and improvements of the charge stripper. The current performance of the RIBF accelerators and future plans to further increase the beam intensity are also presented.

  With the termination of the neutron and proton therapy programs at iThemba LABS, the use of the Separated Sector Cyclotron (SSC) has now shifted to nuclear physics research with both stable and radioactive ion beams, as well as biomedical research. A dedicated isotope production facility with a commercial 70 MeV H-minus cyclotron has been approved and both the cyclotron and isotope production target stations will be housed in the vaults that were previously used for the therapy programs. The status of this new facility will be reported. In the future the SSC will mostly be used for nuclear physics research, as well as the production of isotopes that cannot be produced with the 70 MeV H-minus cyclotron. At present the production of the alpha-emitting radionuclide Astatine (211At) with a 28 MeV alpha beam is being investigated. Progress with the construction of a facility for production of radioactive beams will be discussed. There will also be reports on development work on the ECR ion sources and progress with implementation of an EPICS control system.

  The brand-new Superheavy Element Factory at the Flerov Laboratory of Nuclear Reactions (FLNR) in JINR, Dubna, is under completion, with the high-current DC-280 cyclotron fully installed and tested having Argon beams available for first tests. To improve the efficiency of studies on heavy and superheavy nuclei, it will deliver a wide range of species with high intensity, which in turn require effective separators providing high suppression of unwanted reaction products. The first experiment fed by the cyclotron, GFS-2, is a universal gas-filled separator for synthesis and study of the properties of heavy isotopes, based on the QvDhQvQhD scheme. The presentation describes its study and design in close collaboration between FLNR and Sigmaphi, starting from the initial demand in 2015 and going through the different steps, up to its construction in 2017 and installation in 2018. A second system, GFS-3 is ready to be installed by the end of 2019.
