CENPA has a High Voltage Engineering Corporation Model FN tandem Van de Graaff accelerator purchased in 1966 that has been in continuous use performing a wide variety of accelerator based experiments. In 1995 it was adapted to use an (optional) terminal ion source and a non-inclined tube #3, which enables the accelerator to produce high intensity beams of hydrogen and helium isotopes at energies from 100 keV to 7.5 MeV. The accelerator and its associated ion sources are operated and maintained by staff and students at CENPA. The graduate students and undergraduate hourly employees are trained to operate and service the ion sources and the accelerator in the facility. Experiments in nuclear physics and astrophysics for PhD thesis work as well as graduate and undergraduate projects are done annually using the accelerator. Outside users are also welcome and are frequently accommodated by the lab. Please contact us for rates and availability.

Several additional ion species are available including the following: Mg, Al, Si, P, S, Cl, Fe,
Cu, Ge, Se, Br and Ag. Less common isotopes are generated from enriched material. We
recently have been producing the positive ion beams of the noble gases He, Ne, Ar, and Kr at
ion source energies from 10 keV to 100 keV for implantation, in particular the rare isotopes
21Ne and 36Ar. We have also produced a separated beam of 15-MeV 8B at 6 particles/second.
