Preparation of calcium-separated isotope targets using small samples
Conference

OSTI ID:4078488
Targets are routinely evaporated using a few milligram quantities of separated isotopes of calcium with reducing agents. The source to target distance is 3.0 cm with the substrate, if necessary, as thin as 15 $mu$g/cm$sup 2$ carbon or 100 $mu$g/cm$sup 2$ of gold. A tantalum closed boat, heat shield, and special collimator system are used. (auth)
