  IsoDAR is an experiment proposed to look for the existence of sterile neutrinos. These are additional neutrino states beyond the "standard" 3-nu paradigm, are predicted to exist to explain anomalies in several neutrino experiments. In IsoDAR (Isotope Decay At Rest), electron antineutrinos produced in a target ~15 meters from a kiloton-scale detector would oscillate into and out of the sterile state within the extent of the detector, producing a sinusoidal event rate as a function of distance from the target. The nu-e-bar flux arises from decay of 8Li, produced when a high-current beam of protons or deuterons strikes a beryllium target either directly, or via secondary neutrons that interact in a large, ultra-pure 7Li sleeve surrounding the target. A compact Q/A = 0.5 cyclotron with top energy of 60 MeV/amu will be installed underground close to KamLAND. This cyclotron is a prototype for the DAEδALUS cyclotron chain (Paper WEPPT030). With a central field of 1.075T, it will operate in the 4th harmonic. Preliminary designs will be described, as well as possible solutions for transport and assembly of the machine through the very constricted access apertures of the Kamioka mine.
