The creation of a specific heavy ion residue via heavy ion fusion can usually be achieved through a number of beam and target combinations. Sometimes it is necessary to choose combinations with rare beams and/or difficult targets in order to achieve the physics goals of an experiment. A case in point was a recent experiment to produce (sup 152)Dy at very high spins and low excitation energy with detection of the residue in a recoil mass analyzer. Both to create the nucleus cold and with a small recoil-cone so that the efficiency of the mass analyzer would be high, it was necessary to use the (sup 80)Se on (sup 76)Ge reaction rather than the standard (sup 48)Ca on (sup 108)Pd reaction. Because the recoil velocity of the (sup 152)Dy residues was very high using this symmetric reaction (5% v/c), it was furthermore necessary to use a stack of two thin targets to reduce the Doppler broadening. Germanium targets are fragile and do not withstand high beam currents, therefore the (sup 76)Ge target stacks were mounted on a rotating target wheel. A description of the (sup 76)Ge target stack preparation will be presented and the target performance described.
