Seeking Postdoctoral Researcher, Research & Development Scientist or Technical Staff I (25-3343)

Laboratory

Accelerator Group
RIKEN Nishina Center for Accelerator-Based Science
(Group Director: Osamu Kamigaito)

Outline of Laboratory

Promoting science and technology related to "element transmutation" founded by Dr. Yoshio Nishina more than 80 years ago, RIKEN Nishina Center for Accelerator-Based Science challenges two ultimate questions: "How are elements created in the universe?" and "Can human beings freely transmute elements?" By returning the research results obtained to society, we are trying to solve the environmental, energy and resource problems faced by humankind.
The Nishina Center operates the RI Beam Factory (RIBF), the world's highest performing heavy ion accelerator facility where radioisotopes that do not exist in nature are artificially created. The Nishina Center promotes researches on the synthesis of superheavy elements with one prime example being nihonium, researches in the fields of magic numbers, nucleosynthesis in the universe, and reducing radioactive waste, as well as theoretical research linking these fields.

The accelerator group pursues various upgrade programs of the next-generation heavy-ion accelerator facility, RI-Beam Factory (RIBF), to improve the accelerator performance and operation efficiency. We are also actively promoting the applications of the accelerator facility to a variety of research fields. The cyclotron team’s mission is to have stable operation of cyclotrons for high power beam operation.
