Research Areas

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.

Research Subject

  1. Construction, improvement and operation of BigRIPS separator and its related research instruments
  2. Research and development on RI-beam production and RI-beam separator issues
  3. Related research using RI beams
