We investigate the radiation response of nanotwinned Cu by using in situ Kr ion irradiation technique inside a transmission electron microscope. In comparison with coarse grained Cu, nanotwinned Cu exhibits smaller defect size and lower defect density. In situ studies also show that twin boundaries effectively remove a large number of defect clusters. The life time of defect clusters in nanotwinned Cu is very different from that in its coarse grained counterpart. This study provides further evidence on twin-boundary enabled radiation tolerance in nanotwinned metals.
