Phoswich
WebAbstract Large solid angle position-sensitive phoswich detectors have been constructed to replace smaller units in an array for detecting medium mass fragments (Z less than or equal to 15) in nuclear experiments. The position information was obtained from a time analysis method. 5 refs., 9 figs.
