C182200100017 Thickness of four target segments was 440,340,320 and C182200100018 270 mu-g/cm2. Backing foil thickness was 2.4 mu-g/cm2. C182200100019 DETECTOR (MAGSP) Evaporation residues were separated in gas C182200100020 filled separator BGS and implanted in focal plane C182200100021 detector. C182200100022 (MWPC) A multiwire proportional counter (MWPC) C182200100023 filled with 370-Pa isobutane was placed before the C182200100024 focal plane detector (FPD) to distinguish C182200100025 implantation events from radioactive decay events in C182200100026 FPD. C182200100027 (SISD) Focal plane detector consisted of Si detectors C182200100028 with 48 vertical strips to measure positional C182200100029 information of implantation and decay events. C182200100030 ANALYSIS Transmission efficiency of BGS was determined using a C182200100031 Monte Carlo simulation of trajectories in BGS. The C182200100032 calculated efficiency for 114-XX-285 evaporation C182200100033 residues was 69%.
