A first cyclotron, CYCLONE 30O170300100016 delivers protons of 15.5 MeV on the production target O170300100017 which consists in a 1 cm**3 of water enriched in O-18. O170300100018 The F-18 beam is then produced through the O170300100019 O-18(p,n)F-18 exchange charge reaction. Then the F-18 O170300100020 beam accelerated to the relevant energy with the O170300100021 CYCLONE 110 cyclotron. O170300100022 COMMENT *By authors*.In the present experiment, the O-18 O170300100023 content was evaluated using the difference of the O170300100024 energy loss between F-18 and O-18 in a thick aluminum O170300100025 foil, approx. 670 mug/cm** thick, placed before the O170300100026 target. O170300100027 SAMPLE A 70 mug/cm**2 polyethylene CH2 targets was used. O170300100028 METHOD (EXTB) A 18-F radioactive beam, ionized to 2+ state. O170300100029 (TOF) O170300100030 (COINC) Alpha-particles were detected in coincidence O170300100031 with O-15 ions. O170300100032 ADD-RES (COMP) The framework of the R-matrix model. O170300100033 DETECTOR (SPEC) The products of the H(F-18,a)O-15 reaction were O170300100034 detected using the multi-strip silicon detector LEDA. O170300100035 These detectors are composed of 8 sectors, each O170300100036 divided into 16 radial strips. O170300100037 The energy calibration of the 256 strips was performed O170300100038 with a calibrated 3 alpha-source(Pu-239, Am-241 and O170300100039 Cm-244) whereas the TOF calibration was performed with O170300100040 a precision pulse generator. O170300100041 MONITOR (6-C-12(9-F-18,EL)6-C-12,,DA) The number of incident O170300100042 F-18 ions was determined and detected in the LEDA2 O170300100043 detector.
