Description

The Radioactive Isotope Beam Factory (RIBF) at RIKEN is an accelerator-based experimental facility capable of producing energetic radioactive isotope beams by employing the large-acceptance fragment separator BigRIPS and the superconducting ring cyclotron SRC.
At RIBF, several experimental programs are underway to determine the nuclear equation of state (EoS) through studies of both nuclear structure and nuclear reaction.
So far, these efforts have included: proton elastic scattering measurements for neutron-rich isotopes, systematic measurements of the isoscalar giant monopole resonances across isotope chains, and the determination of nuclear radius from the measurement of reaction cross section.
The nuclear EoS for neutron-rich high-density matter has also been investigated using RI beams as projectiles in heavy-ion collisions — a unique method to create high-density matter in the laboratory.

In this talk, I will present the next-generation experimental programs at RIBF aimed at studying the density dependence of the symmetry energy, along with upgrade plans for RIBF to remain competitive with other next-generation RI-beam facilities.
