Description
Summary:A new detector array characterized by compact structure and large solid-angle coverage was designed for radioactive ion beam (RIB) experiments and measuring multi-particle correlations. A Monte Carlo simulation was performed to explore the effects of beam drifts in different directions and distances on the angular distribution of the Rutherford scattering, as measured by the detector array. The results indicate that when the beam drift distance is less than 2.0 mm, the symmetry of the detector array can maintain a count error of less than 5 % . This confirms the property of the detector array for RIB experiments. Furthermore, the simulation was validated through the elastic scattering angular distributions of 6 , 7 Li measured by the detector array in 6 , 7 Li + 209 Bi experiments at different energies.
