Outline of Final Research Achievements

Purpose of this research is an improvement of efficiency in mass measurement at Rare-RI Ring (R3) by using a particle selection system. This system selects particles to be injected into R3 using the flight time and energy loss information obtained from detectors at beamline.
Development of the particle selection system have been succeeded smoothly and we have been developed some modules. We can select the particles flexibly by using this system. Mass measurement of Ni isotopes at R3 using this system was performed.
