The 12″ cyclotron at the Radiation Facilities was built by Tim Koeth as a personal project. The cyclotron is used primarily as a educational tool for accelerator physics. It is unique in that it is built with may interchangeable components that can be swapped out to to demonstrate the effects on the beam.

Although it is primarily used as an educational tool the cyclotron is also capable of proton, deuteron, or alpha particle bombardment of small samples. Protons can be accelerated up to 1 MeV, deuterons and alpha particles up to 600 keV. By accelerating a deuteron beam into a deuterated titanium target pulsed neutron production is also possible.
