C228300100013 SAMPLE Windowless gas target with an effective length of C228300100014 12.3 cm was operated at He pressures ranging from C228300100015 7.08 to 9.13 Torr. This resulted in target thicknesses C228300100016 ranging from 55 to 75 keV in the CM system. C228300100017 DETECTOR (BGO) DRAGON's gamma detector array consists of 30 C228300100018 bismuth germanate (BGO) scintillators in a close- C228300100019 packed geometry covering 92% of the solid angle C228300100020 surrounding the gas target. C228300100021 (MAGSP) Heavy reaction products were momentum C228300100022 analyzed in DRAGON spectrometer and identified in C228300100023 spectrometer focal plane. C228300100024 (MCPLT) Heavy reaction products were identified in C228300100025 focal plane using time-of-flight system consisting of C228300100026 two microchannel plates C228300100027 (IOCH) A multi-anode ionization chamber measured the C228300100028 energy loss and total kinetic energy of heavy ions C228300100029 transmitted to DRAGON's focal plane. C228300100030 METHOD (TOF,EDE,COINC) C228300100031 INC-SOURCE An isotopically pure beam of 34S ions was generated C228300100032 by the Supernanogan electron cyclotron resonance C228300100033 plasma source using a gas supply of SF6 enriched in C228300100034 34S. The beam was accelerated through the ISAC-I C228300100035 Radio-Frequency Quadrupole and the Drift-Tube Linac C228300100036 to energies between 20.23 and 25.75 MeV C228300100037 HISTORY (20180405C) Compiled by S.H.
