Abstract
Experiments involving neutron-rich radioactive beams often require a high d etection efficiency for neutron pairs within a small solid angle. The rejec tion of cross-talk events under such conditions has been studied for a modu lar detector array and the optimum array configuration investigated. In par allel, a new algorithm for the rejection of cross-talk events has been deve loped. By grouping detectors into clusters corresponding to a single-incide nt neutron, high multiplicity (M-n greater than or equal to 2) events may b e recognized. Results from Monte-Carlo simulations demonstrating the perfor mances of the algorithm are presented. Finally, the application to two-neut ron interferometry measurements for halo nuclei is discussed.
