D637300100018 The target is sandwiched between carbon films of D637300100019 backing thickness ~20 ug/cm2 and capping thickness D637300100020 ~10 ug/cm2 with carbon backing facing the beam. D637300100021 DETECTOR (SIBAR) Two silicon surface barrier detectors were D637300100022 placed inside the target chamber at angle of +/-25 D637300100023 degree are used to detect elastically scattered D637300100024 particles from the target. D637300100025 These detectors are also used to focus the beam at the D637300100026 center of the target and to normalize ER cross D637300100027 sections. D637300100028 (MAGSP,MWPC) Position-sensitive multiwire proportional D637300100029 counter of dimensions 6 in. X 2 in. detect the ER crossD637300100030 section. D637300100031 A polypropylene foil of thickness 0.5 um separates D637300100032 HYRA electromagnetic section from focal plane. D637300100033 The detector is operated using isobutane gas at D637300100034 2.5 mbar pressure and provide position signals, energy D637300100035 loss (delta E) and timing signal. D637300100036 The pressure of He gas is optimized at 0.3 Torr. D637300100037 The gas-filled region of HYRA is separated from the D637300100038 vacuum region using ~660 ug/cm2 window foil of carbon.D637300100039 The transmission efficiency of HYRA was 28.7+/-4.3%. D637300100040 METHOD (TOF) D637300100041 (ASEP) The heavy ERs are separated from the enormous D637300100042 beam background using hybrid recoil mass analyser D637300100043 (HYRA). D637300100044 CORRECTION The incident energies were corrected for the energy D637300100045 loss of the beam particles in 660 ug/cm2, pressure D637300100046 window foil, 0.30 Torr of He gas between pressure D637300100047 window foil and target (35 cm), 20 ug/cm2 carbon D637300100048 backing and 100 ug/cm2 half thickness of 138Ba.
