	The IsoDAR and DAEδALUS experiments will use cyclotrons to deliver high intensity (10 mA peak current) proton beams to neutrino-producing targets. To achieve these very high currents, we plan to inject and accelerate molecular H²⁺ ions in the cyclotrons. To understand high intensity H²⁺ injection into the central region of a compact cyclotron, and to benchmark space-charge dominated simulation studies, central-region tests are being conducted. Building on the first experiments at Best Cyclotrons, Vancouver (Abstract 1261), a larger-scale test cyclotron will be built at INFN-LNS in Catania. This cyclotron will be designed for 7 MeV/n (Q/A = 0.5; H²⁺ or He⁺+). After the first year of operation dedicated at optimization of the central region for the injection of high intensity Q/A = 0.5 beams, the cyclotron will be modified to allow the acceleration of H⁻ up to an energy of 28 MeV. The main characteristics of the machine and the planned test stand will be presented.

The IsoDAR and DAEδALUS experiments will use cyclotrons to deliver high intensity (10 mA peak current) proton beams to neutrino-producing targets.

To understand high intensity H²⁺ injection into the central region of a compact cyclotron, and to benchmark space-charge dominated simulation studies, central-region tests are being conducted. Building on the first experiments at Best Cyclotrons, Vancouver (Abstract 1261), a larger-scale test cyclotron will be built at INFN-LNS in Catania.
