2nd Symposium on TOPTIER Platform in Extreme Rare Isotope Science
RIKEN Wako Campus

Following the successful launch of the TOPTIER (TOP-Tier Platform In Extremely Rare Isotope Science) project, we are pleased to announce that the second meeting will be held at the RIKEN Nishina Center (RNC) from August 19 to 21.
The TOPTIER project, a joint effort between Korea’s RAON facility of IRIS/IBS and Japan’s RIBF of RIKEN, supported by Korea’s Ministry of Science and ICT (MSIT), is dedicated to advancing research in rare isotope science. The second meeting will further strengthen collaboration, review ongoing progress, and outline the next steps toward developing cutting-edge technologies for the generation and study of extremely rare isotopes.
We look forward to continued engagement and valuable contributions from all participants as we move forward with this important scientific initiative.
