OEDO, the deceleration and focusing device at RIBF, and the nuclear astrophysics program with OEDO

Nobuaki Imai (Centre for nuclear studies, Tokyo, Japan)

OEDO is a new beam line to decelerate and focus fast radioactive isotope beams at RIBF. A high frequency RF deflector synchronized with the Superconducting Cyclotron in RIBF can make a relatively small beam spot of the decelerated RI beam around 20 MeV/nucleon on a secondary target. OEDO was installed at the beam line equipped with the SHARAQ spectrometer. By using its first half, QQD magnets, the reaction residue can be momentum-analyzed. The combination of the decelerator and the spectrometer is unique in the world. By employing both OEDO and SHARAQ, some (d,p) reactions have been measured in inverse kinematics as the surrogate reactions of astrophysical interest.
In this talk, we will explain the principles of OEDO with some properties of the decelerated RI beams. We will also talk about the recent experimental results and future perspectives.
