Research Areas

This team is in charge of maintenance and improvement of detectors which are used at BigRIPS separator and its succeeding beam lines for beam diagnosis and particle identification of RI beams. We are also engaged in R&D of new detectors that can be used for higher-intensity RI beams. In addition, we are doing the R&D which uses the pelletron accelerator together with other groups.

Research Subject

  1. Maintenance and improvement of the beam-line detectors which are used at BigRIPS separator and its succeeding beam lines
  2. Development of new beam-line detectors with radiation hardness and tolerance for higher counting rates
  3. Management of the pelletron accelerator and R\&D which uses the pelletron
