A fragment separator, the Radioactive Ion Beam Line in Lanzhou (RIBLL), has been constructed at the Heavy Ion Research Facility of Lanzhou and in operation since January 1998. The RIBLL was designed to be a double achromatic anti-symmetry spectrometer with a total length of 35 m.
It has a confguration of F0-Q2DQ2-F1-Q2DQ2-F2-Q2DQ2-F3-Q2DQ2-F4 with three focal points (F0, F2 and F4) and two focal planes (F1, F3). Q and D mean quadrupole and dipole respectively here, and some main features of the RIBLL are listed below.
