... Although the early pelletrons were designed to operate at high voltages for nuclear research, the most recently built machines were used for a variety of applications, such as ion implantation, accelerator mass spectroscopy, and as analytical tools. When Ray returned to Madison at the end of the war, he moved into a house in the country just outside Madison.
