O123300100015 SAMPLE High purity Ti-foils (99.6% purity, 20-mm diameter, O123300100016 ~0.5-mm thick) were used. O123300100017 FACILITY (CYCLO,1USAHRV) O123300100018 36-Cl concentrations were determined using the ANTARES O123300100019 AMS facility at ANSTO. O123300100020 METHOD (STTA,CHSEP) O123300100021 (BCINT) Transmission ionisation chamber for measurementO123300100022 the incident proton current. The chamber was O123300100023 recalibrated at each energy point. O123300100024 (AMS) Cl-36 identification was achieved with a Bragg O123300100025 detector using P10 gas and Cl-35,37 isotope tails wereO123300100026 suppressed using a Wien velocity filter. O123300100027 Each sample was measured 3-5 times, corrected for O123300100028 fractionation and dead-time and then normalised to O123300100029 Cl-36/Cl standard. Where applicable, ratios were alsoO123300100030 carefully corrected for effects of varying and O123300100031 excessive S-36 rates which cause integrated Cl-36 ratesO123300100032 to be enhanced above their true value. Error O123300100033 propagation included a 5% reproducibility uncertainty,O123300100034 a 1-6% statistical uncertainty and a 0-10% uncertainty O123300100035 in calculating the correction factor due to S-36 O123300100036 interference.
