S027200100016 DETECTOR (MAGSP) The evaporated residues (ERs) yielded in the S027200100017 fusion evaporation reaction 40Ar+186W were filtrated S027200100018 by the Spectrometer for Heavy Atoms and Nuclear S027200100019 Structure (SHANS). S027200100020 (PS,SISD,SI,MWPC) The ERs were implanted into three S027200100021 300 um thick position-sensitive strip detectors (PSSDs)S027200100022 with each active area of 50 X 50 mm2. Eight additional S027200100023 non-position-sensitive side silicon detectors (SSDs) S027200100024 were mounted upstream. The total detection efficiency S027200100025 for the emitted alpha was measured to be about 72%. S027200100026 To distinguish the alpha events from the implanting S027200100027 events, two multi-wire proportional counters (MWPCs) S027200100028 were mounted 15 cm and 25 cm upstream from the PSSDs. S027200100029 Three extra non-position-sensitive silicon detectors, S027200100030 featuring the same size as the PSSDs, were installed S027200100031 side by side after the PSSDs to provide the veto S027200100032 signals from the light particles passing through S027200100033 the PSSDs. S027200100034 (HPGE) Near the charged particle detection system, S027200100035 two High Purity Germanium (HPGe) detectors and one S027200100036 clover detector were mounted at the right side, S027200100037 downward, and downstream, respectively.
