    A new horizontal‐type 6 MV Pelletron tandem accelerator was designed and developed by the National Electrostatics Corp., USA in collaboration with the University of Tsukuba as part of the post‐quake reconstruction project. The main accelerator (model 18SDH‐2 Pelletron) is a dual acceleration electrostatic accelerator. The accelerator tank is 2.74 m in diameter and 10.5 m long. The generator operates reliably to terminal voltages as high as 6.5 MV. Stability is estimated to be better than 1 kV at a 6.0 MV terminal voltage. Maximum beam currents are predicted to be up to 3 μA for proton and 50 μA for heavy ions. It was installed at the University of Tsukuba in March 2014. We started routine experiments on ion beam applications by means of the new system since March 2016. The 6 MV Pelletron tandem accelerator will be used for various ion‐beam research projects, such as AMS, IBA, ion irradiation, and nuclear physics.

    We have been studying a stable isotope separation/enrichment using Ion-Cyclotron-Resonance (ICR) method. Since most of basic technologies for the ICR method has been accumulated and exits in the accelerator science, we could start the study using equipment available in KEK. Here, we report the status of the study. While a slight effect of enrichment for zinc isotopes has been observed, many problems still remain. We are looking forward to receiving helpful suggestions.

    We recently conducted the performance test for the Rare-RI Ring (R3) using exotic nuclei. A novel injection method, isotope-selectable self-triggered injection, was established. An isochronous condition for the reference nuclide was tuned in an order of ppm. We succeeded in extracting several exotic nuclei from the R3, and are verifying the principle of the mass determination.
