These TiN were prepared by evaporation on D047100100012 high-purity Cu foils with a thickness of about 20 D047100100013 lm. The produced 26Al nuclei were implanted into the D047100100014 Cu foil.The Cu foils were tightly attached to a beam D047100100015 dump which was used as Faraday cup. Watercooling was D047100100016 used to decrease the target temperature, so that the D047100100017 targets could withstand 16O beam (16O4+ or 16O3+) D047100100018 intensities of 3 mu-A.
