The guard foils were sufficiently thick C201100100013 to compensate for 24Na recoil losses from the central C201100100014 foil. Targets for early experiments contained C201100100015 polyethylene foils to measure the C201100100016 27Al(p,3pn)24Na/12C(p,pn)11C ratio C201100100017 DETECTOR (GELI) Gamma rays from decay of 24Na were detected C201100100018 with Ge(Li) detectors in two geometries, at nominal 5 C201100100019 and 10 cm distances from the cryostat face. C201100100020 METHOD (ACTIV) A raw cross section for each experiment was C201100100021 calculated from the mean 24Na disintegration rate C201100100022 extrapolated to the midpoint of the irradiation and C201100100023 the proton fluence determined by the current C201100100024 transformers.
