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 inportantly 3He and 4He. Among the beams available from the sputter source is the radioactive isotope 14C.

The beams from the Tandem are injected into the linac, which more than doubles their energy. The superconducting linear accelerator consists of twelve accelerating resonators installed in three cryostats, plus buncher and re-buncher each located in their own cryostats. The resonators are niobium-on-copper "split-ring" resonators produced by Argonne National Laboratory. The cryostats were designed and built at FSU. All accelerating resonators are designed for β=0.1.

The laboratory has developed an upgrade plan to the linear accelerator to increase the energy and mass-range of beams available for experiments. The upgrade entails the increase of cryogenic capacity by the addition of a second Linde-1630 liquid Helium refrigerator (completed 2013), the addition of a high-pressure cleaning facility and the addition of two cryostats to the linac. We already acquired the eight aqdditional split-ring resonators and the associated electronics as surplus from Kansas State University.
