Radioactive Ion-Beams At Hirfl

At the first stage the Radioactive Ions Beam Line in Lanzhou (RIBLL) is a Projectile Fragmentation (PF)-type Radioactive Nuclide Beam (RNB) facility, in which neutron-rich and proton-rich RMB are produced by means of the energetic projectile fragmentation at around 0 degrees. The mechanisms of RNB production, separation, transportation and identification are introduced; the structure and characteristics of this system are described. The results of test run are also reported in this paper.
