D029400100011 A 12 mg/cm2 target was used to give larger counting D029400100012 rates when energy resolution was not a limiting factor;D029400100013 otherwise a 6 mg/cm2 target was used. D029400100014 DETECTOR (MAGSP) Two different detection systems were used to D029400100015 measure the positions of the proton groups in the D029400100016 focal plane. The first system consisted of two D029400100017 wedge-shaped scintillators with a dE/dx counters D029400100018 placed in front of each wedge. These counters consistedD029400100019 of 0.5 mm thick NE 102A plastic scintillator mounted D029400100020 on perspex light guides. D029400100021 In the second an acoustic spark chamber was used. D029400100022 The chamber was triggered using the coincidence pulse D029400100023 obtained from the two dE/dx counters placed behind the D029400100024 spark chamber. These counters consisted of 0.6 mm thickD029400100025 NE 102A plastic scintillator mounted on perspex light D029400100026 guides.
