Nuclear physicists had a need for thin targets of a wide variety of isotopes for use with accelerator beams. These targets were normally manufactured by vacuum evaporating mg quantities of the often-rare isotope on thin polyvinyl acetate (PVA) films. Three specimens, glued to the tops of specimen jars for demonstration purposes, are here. One is simply a thin layer of PVA, the second is a thin, gold target evaporated on PVA and the third is a thin, tungsten target evaporated on a metal backing. The purpose of the latter is unknown. In addition to targets of this type, thin stripper foils of similar size and geometry were produced in this lab and were used at the TASCC facility to strip electrons from beams to increase their charge before further acceleration. Two signs from the laboratory complete the artifact.
