C144600100016 DETECTOR (SIBAR) Recoil a particles and 15O ions from the C144600100017 1H(18F,a)15O reaction were detected in coincidence by C144600100018 two large area silicon detector arrays (SIDAR and C144600100019 MINI, respectively). The SIDAR was tilted forward 43 C144600100020 degree from the perpendicular to the beam axis in C144600100021 order to cover a large angular range (29 degree < C144600100022 Theta-lab < 73 degree), while the smaller annular C144600100023 detector (MINI) covers 11.5 degree < Theta-lab < C144600100024 22.5 degree) C144600100025 (IOCH) Scattered 18F and 18O ions were also C144600100026 continuously detected by a gas-filled ionization C144600100027 counter enabling a constant monitor of the beam C144600100028 composition C144600100029 SAMPLE A 70 microg/cm2 CH2 target.
