Towards the full realization of the RIBLL2 beam line at the HIRFL-CSR complex

摘要

The RIBLL2 in-flight separator at IMP, the secondary beam line between twostorage rings at the \blue{\uwave{Heavy Ion Research Facility in Lanzhou(HIRFL-CSR)}}, has been commissioned to study the rare-isotope beam (RIB)physics at around 300 MeV/nucleon for the first time, in combination of theexternal target facility (ETF). The unambiguous particle identification in massand charge states for $^{18}$O and $^{40}$Ar fragments has been achieved inrecent experiments. A full realization of RIBLL2 will open many potentials toaddress important RIB physics problems at around 300 MeV/nucleon.
