RIKEN Nishina Center for Accelerator-Based Science BigRIPS Team

Team Leader: Nobuhisa Fukunishi (D.Sc.)

Research Summary

Nobuhisa Fukunishi

This team is in charge of design, construction, development and operation of BigRIPS in-flight separator and its related research instruments such as ZeroDegree spectrometer at RI beam factory (RIBF). They are employed not only for the production of RI beams but also various kinds of experimental studies using RI beams.
