“…a K=69 Sector Focus Cyclotron (SFC) for low-energy ions and a K=450 Separate Sector Cyclotron (SSC) for intermediate-energy ions. In order to obtain low-energy intense secondary beams by transfer reaction, a setup similar to CRIB was recently installed including a gas target system at the entrance position of RIBLL [30]. The new setup enables the primary beam from SFC to be transported directly to RIBLL, i.e.…”

Abstract. 22 Na is an important isotope for the study of extinct radioactivity, meanwhile its sufficiently long half life provides the possibility to observe live 22 Na in nearby nova explosions. The 22 Na(p,γ) 23 Mg is one of the key reactions that influence the 22 Na abundance in nova ejecta. To study the proton resonant states in 23 Mg relevant to the astrophysical 22 Na(p,γ) 23 Mg reaction rates, two measurements have been carried out at the CRIB separator of University of Tokyo, and the RIBLL secondary beamline in Lanzhou, respectively. The 22 Na secondary beam was produced via the 1 H( 22 Ne, 22 Na)n charge exchange reaction. Thick-target inverse-kinematics method is applied to obtain the excitation function of 22 Na+p elastic scattering. Extended gas target and solid state polyethylene foil were used in the two measurements, respectively, to map the different excitation energy region of the compound nucleus 23 Mg. Several new resonant levels are observed and their contribution to the 22 Na(p,γ) 23 Mg reaction rate is evaluated.

The performance of a four fold segmented clover detector coupled to a CsI-suppressed shield has been tested using several standard radioactive sources. The summing characteristics, hit patterns and absolute efficiency were measured in both crystal and clover modes. Peak-to-total ratios of 57.3% and 45.6% in suppressed clover mode have been determined for 137 Cs and 60 Co sources, respectively. A Geant4 simulation of the suppressed clover detector, including the segmentation of the germanium crystals, has been created, and the simulation results agreed very well with the experimental data.
