This second generation radioactive ion beam facility will be constructed at GANIL and be operational in 2012 with stable beams and 2013 with radioactive ion beams. The aim of the installation is to produce high-intensity, high-quality radioactive ion beams of isotopes from large regions of the chart of nuclei in the range of 3 to 240u. Following description corresponds to the conceptual design study of a low energy RIB transport line for the SPIRAL 2 project.

236U is a long-lived radioactive isotope with a half-life of 2.342(3) ×107 a, which produced principally by thermal neutron capture on 235U. 236U is potentially applied in geological research and nuclear safeguards. Accelerator mass spectrometry (AMS) is presently the most sensitive technique for the measurement of 236U. A method for AMS measurement of long-lived heavy ion 236U was developed at CIAE with the set up the AMS dedicated injector and the newly proposed 208Pb16O2- molecular ions for the simulation of 236U ion transport. A sensitivity of lower than 10-10 has been achieved for isotopic ratio 236U/238U in present work.
