Two detectors L025200100017 provided spatial information as well as the start L025200100018 signals for the double time-of-flight measurement, L025200100019 which permitted the fragment mass information to be L025200100020 deduced. Two hemispheres, each consisting of five L025200100021 independent detectors, were mounted a distance of L025200100022 12.5 cm from the target center, and covered a solid L025200100023 angle of almost 4pi. L025200100024 (NAICR) The tagging efficiency was measured in L025200100025 separate calibration runs with a 25.4 cm x 35.6 cm L025200100026 NaI detector using a very low intensity electron beam L025200100027 with an endpoint energy of 21 MeV to produce the taggedL025200100028 photons. L025200100029 SAMPLE A homogeneous 7cm x 10cm fissile target of 400 mu-g/cm2L025200100030 of 238U evaporated onto a 200mu-g/cm2 mylar foil used. L025200100031 The target was sandwiched between the two inner L025200100032 detectors, which are separated by a distance of 1 cm. L025200100033 METHOD (TOF) L025200100034 HISTORY (20190522C) OG.
