A test-bench for isotope separator on-line of Beijing radioactive ion-beam facility

A test-bench for isotope separator on-line of Beijing radioactive ion-beam facility (BRISOL) has been built in China Institute of Atomic Energy (CIAE). The test-bench consists of target station, charge exchange cell, mass separator, quadrupole, hexapole, multipole and beam diagnostic system. It is nearly the same configuration as the first stage of BRISOL and all these components will be used on the BRISOL. A series of experiments have been carried out on this test-bench, and the primary results showed that all the components worked well. A Li+ beam has been generated from the positive surface-ionization source and its emittance and the transmission of the beam line have been measured. The design, construction and experimental results of this test-bench have been presented.
