C228100100011 (VDGT,1USAANL) The Argonne FN tandem accelerator. C228100100012 SAMPLE (12-MG-26,ENR=0.994) 26Mg foils (99.4% isotopic C228100100013 abundance, 3.5-3.9 mg/cm2 thick, ~ 1 mg total C228100100014 material). C228100100015 DETECTOR (IOCH) C228100100016 METHOD (AMS) Stacks of up to three foils were bombarded with C228100100017 protons. After the irradiation, known amounts of 27A1 C228100100018 powder (15-25 mg Al) were added to each of the 26Mg C228100100019 foils. It is assumed that the 26Al produced in the C228100100020 26Mg foils is converted to Al203 with the same C228100100021 efficiency as the added 27Al. The MgO + Al203 powder C228100100022 (16-40 mg) was then thoroughly mixed with 140 mg Zn C228100100023 powder and pressed to solid pellets of 6.4 mm C228100100024 diameter, which were mounted to the 10-position cone C228100100025 wheel of the inverted Cs-beam sputter source at the C228100100026 Argonne tandem. The split-pole focal plane detector C228100100027 is a position sensitive ionization chamber which C228100100028 generates position, differential energy loss and C228100100029 total energy signals, thus allowing complete mass and C228100100030 nuclear charge identification. C228100100031 ERR-ANALYS (DATA-ERR) The main contributions to the errors arise C228100100032 from statistics.
