Introduction nuCARIBU is an upgrade to the existing CAlifornium Rare Isotope Breeder Upgrade (CARIBU) radioactive ion beam (RIB) facility. nuCARIBU will integrate neutron induced fission of actinide foils as the RIB production mechanism into the existing collection and separation equipment. The p-7Li reaction will produce neutrons, which will be thermalized in a moderator, and subsequently captured by the actinide foil, fission target. Fission fragments produced by the neutron capture reactions will be collected in a high purity He gas catcher. Figure 1 shows the main components of the nuCARIBU fission fragment production. Figure 1: The primary components of the nuCARIBU fission fragment production. A cyclotron will provide the protons with an average energy of 6.132 MeV. After extraction a quadrupole triplet will be used to properly focus the beam. The axis of the cyclotron will be 30 in (76.2 cm) higher than the target. A vertical magnetic chicane will deliver the proton beam to the needed height. The chicane specifications have been estimated based on the beam distribution and space available. Figure 2 highlights the major components of the transport system, and Figure 3 shows the detailed center trajectory of the beam through the chicane.
