nuCARIBU will fundamentally change the way neutron-rich, heavy (A>100) radioactive ion beams (RIB) are created at ATLAS. Protons from a 6 MeV, 0.5 mA cyclotron will bombard a 7Li target to generate neutrons via the p-7Li reaction. These neutrons will be thermalized in a moderator and then captured in an actinide foil, e.g. 235U. Heavy fission fragments resulting from the neutron capture reactions will be formed into ion beams in an existing gas catcher and separator system. This new production mechanism will replace the current source of radioactive ions, a thin plating of spontaneously fissioning 252Cf. nuCARIBU is expected to increase the overall intensity of n-rich ions, and improve the consistency and reliability of RIB at ATLAS. The cyclotron has demonstrated full beam production, and the results of initial proton extraction tests agree well with simulations. This paper will present the results of the cyclotron commissioning, neutron production, and initial radioactive beam production.
