	In order to study and optimize the ion source and injection system of our multiple cyclotron products, Best® Cyclotron Systems Inc. (BCSI) has assembled in its Vancouver office a 1 MeV cyclotron development platform. To accommodate different injection line configurations, the main magnet median plane is vertically oriented and rail mounted which also allows easy access to the inner components. In addition, the main magnet central region is equipped with interchangeable magnetic poles, RF elements, and inflector electrodes in order to replicate the features of the simulated cyclotrons. Multiple diagnostic devices are available to fully characterize the beam along the injection line and inside the cyclotron. This paper will describe the design of two system configurations: the 60 MeV H²⁺ for the DAEΔALUS experiment (MIT, BEST, INFN-LNS) and the BCSI 70 MeV H⁻ cyclotron.

	SPES (Selective Production of Exotic Species) is an INFN project with the aim to develop a Radioactive Ion Beam (RIB) facility as an intermediate step toward EURISOL. The SPES Project is under realization at the INFN Legnaro National Laboratories site. The SPES Project main goal is to provide a production and accelerator system of exotic beams to perform forefront research in nuclear physics by studying nuclei far from stability. The SPES Project is concentrating on the production of neutron-rich radioactive nuclei with mass in the range 80-160. The final energy of the radioactive beams on target will range from few MeV/u up to 11 MeV/u for A=130[1]. The SPES facility acceleration system will be presented.

	Best Cyclotron Systems Inc. is presently developing a test facility for beam injection into a center region cyclotron operating at maximum 1MeV. The test stand cyclotron will operate at various fixed frequencies that will cover the entire range from 49MHz to 80MHz as estimated for the current cyclotron models under development at BCSI. The resonator was designed with a variable coaxial section allowing for the frequency to be continuously adjusted as required for the particular model in study. Having interchangeable dee tip geometries presented various thermal management challenges which have been addressed. Three operational frequencies, 49MHz, 56MHz and 73MHz have been simulated with CST Microwave Studio. The paper will report the theoretical parameters of the cavity, mechanical design considerations and resonator commissioning on the first operational frequency of 49MHz.

	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.
