Physics -- Elements at Extremes (IMAGE) DOE/Oak Ridge National Laboratory Caption Position-sensitive silicon detectors form the "nerves" of the Super Oak Ridge Rutgers University Barrel Array and yield high spatial resolution that enabled the Sn-132 experiment at ORNL -- the first neutron-removal reaction on such a heavy, neutron-rich nucleus. The array, installed at Michigan State University, should begin operations in 2022.
