Research Field and Overview

RIKEN's research is based on synthesis and interdisciplinarity, and with free thinking as its basic philosophy, RIKEN promotes research that goes beyond the boundaries of conventional research fields, while at the same time responding to the needs of society from a strategic perspective.

RIKEN invites applications for the position of Director, Instrumentation Development Group (indefinite-term employment position) to serve in a leadership position in the following research area. The successful candidate will be responsible for directing research projects from a medium-to-long-term perspective.

Field: Development, upgrade and operation of the core experimental instrumentations of the heavy ion accelerator facility
RIKEN Nishina Center for Accelerator-Based Science (RNC) operates RI Beam factory (RIBF) equipped with powerful heavy-ion accelerators, in-flight separator of the radioactive ion beams, and unique core experimental equipment. At RIBF, the Instrumentation Development Group has been developing and constructing three core experimental apparatuses, i.e., the Self-Confining RI Ion Target (SCRIT) for the RI and electron scattering experiments, heavy-ion storage ring named Rare-RI Ring (R3) for the precise mass measurement of short-lived nuclei, and the slow RI beam generator (SLOWRI), that are now being put into operation for world-leading experiments.

The new head of the laboratory will be responsible for the development, construction, maintenance, management, operation, and upgrading of the above three core experimental devices, through supervision of the three teams that are in charge of the devices. The successful candidate is strongly expected to promote collaborative research with domestic and overseas institutions using the core experimental devices, as well as to develop the core experimental equipment for further improvement of its performance and efficient operation. Moreover, he or she is expected to utilize the trained technical personnel for the development of instruments based on the future plan of the Nishina Center, while aiming for new devices that will pave the way for the next generation of heavy ion science.
