RIKEN Nishina Center for Accelerator-Based Science Detector Team

Team Leader: Hiromi Sato (D.Sc.)

Research Summary

Hiromi  Sato(D.Sc.)

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.
