  The LNS Superconducting Cyclotron has been operating for almost 20 years. Several beams are currently accelerated and delivered, allowing for a wide variety of experimental activity to be carried out. In addition, clinical activity is regularly accomplished: over 11 years of protontherapy of the eye pathologies, around 300 patients have been treated. This has stimulated a growing number of interdisciplinary experiments in the field of radiobiology and dosimetry. On the side of nuclear physics, a significant achievement is the production of radioactive beams: several rare isotopes are produced mainly exploiting the in-flight fragmentation method. The development activity carried out on several components of the user oriented facility will be described.

  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.
