Description

The next generation of nuclear physics research will require advanced exotic beam facilities based on heavy-ion drivers. Exotic beams of rare nuclei will be produced via fragmentation and fission reactions resulting from a high-energy heavy-ion beam hitting a target. A large aperture fragment separator with superconducting magnets is needed for capture, selection, and transport of rare isotopes for experiments. For rare isotope registration the multi-stage separation is required to provide reasonable rates in detectors located in an analyzing stage. So, the recent experiment devoted to explore the $^{60}$Ca region at the RIKEN RIBF facility [1] demonstrated a necessity to have three-stage separation to approach the neutron-dripline in the calcium region. Another important aspect according to the LISE$^{++}$ code calculations [2] in these new research is multi-step reactions taking into account. Momentum compression technique applied in a fragment-separator wedge-selection section and rare isotope beams slowing down line in front of a gas-cell will be discussed.
