The John D. Fox laboratory operates a two-stage accelerator
comprised of a 9~MV Super-FN tandem van-de-Graaff accelerator and an
8~MV superconducting linear accelerator (LINAC). The Super-FN tandem
is injected by either a NEC SNICS-II cesium sputter ion source, for
most beams created from solid chemicals, or an NEC rf-discharge source
for beams generated from gaseous materials, most
importantly ^{3}He and ^{4}He. Among the beams
available from the sputter source is the radioactive isotope 14C.

A negative beam enters the TANDEM on the Low-Energy (LE) end, and is accelerated towards the High-Energy (HE) end by a voltage potential generated by the van-de-Graff generator consisting of two rotating chains. At the midpoint of the TANDEM, the negative beam strikes a stripper foil which ``strips'' it of electrons, causing the beam to become positive and carry on into the rest of the lab.
