Research Instruments Group

The research instruments group is the driving force at RI Beam Factory (RIBF) for continuous enhancement of activities and competitiveness of experimental research. Consisting of four teams, we are in charge of the construction, operation and improvement of the core research instruments at RIBF, such as BigRIPS in-flight separator, ZeroDegree spectrometer and SAMURAI spectrometer, and the related infrastructure and equipment. We are also in charge of the production and delivery of RI beams using the BigRIPS separator. The group also conducts related experimental research as well as R&D studies on the research instruments.

Research Subjects

• Production and delivery of RI beams and related research
• Construction, operation and improvement of the core research instruments at RIBF and their related infrastructure and equipment
• R&D studies on the core research instruments and their related equipment at RIBF
• Experimental research on exotic nuclei using the core research instruments at RIBF
