Research Areas

In collaboration with research groups in and outside RIKEN, this team designs, develops and constructs the SAMURAI spectrometer and relevant equipment that are and will be used for reaction experiments using RI beams at RI Beam Factory. SAMURAI consists of a large superconducting dipole magnet and a variety of detectors to detect charged particles and neutrons. Based on the outcome from the commissioning experiment in March 2012, the team prepares for first experiments with SAMURAI planned in the year 2012. The team also provides basis for research activities by, for example, organizing workshops and forming a "collaboration" scheme among researchers interested in research with SAMURAI.

Research Subject

  1. Design, development and construction of a large superconducting dipole magnet that will be the main component of the SAMURAI spectrometer
  2. Design, development and construction of various detectors that are used for nuclear reaction experiments using the SAMURAI spectrometer
  3. Preparation for starting experiments using SAMURAI planned in 2012.
