At the first stage the Radioactive Ions Beam Line in Lanzhou (RIBLL) i
s a Projectile Fragmentation (PF)-type Radioactive Nuclide Beam (RNB)
facility, in which neutron-rich and proton-rich RMB are produced by me
ans of the energetic projectile fragmentation at around 0 degrees. The
mechanisms of RNB production, separation, transportation and identifi
cation are introduced; the structure and characteristics of this syste
m are described. The results of test run are also reported in this pap
er.
