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 but 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.
