	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.

MOPPT020	Study of a Superconducting Compact Cyclotron for Delivering 20 MeV High Current Proton Beam	76
	M.M. Maggiore INFN/LNL, Legnaro (PD), Italy L. Bromberg, C.E. Miller, J.V. Minervini, A. Radovinsky MIT/PSFC, Cambridge, Massachusetts, USA
	Compact cyclotrons which accelerate high current of H⁻ ions in the range of 10-30MeV have been widely used over the last 25 years for medical isotope production and other applications. For a number of these, low weight, low power consumption, portability or low radiation background are key design requirements. We have evaluated the feasibility of a compact superconducting cyclotron that would provide proton beams up to 20 MeV by accelerating H⁻ ions and extracting them by the stripping process with current of 100uA. The study demonstrates that the survival of the H⁻ ion under high magnetic field environment could be large enough to guarantee low beam losses as long as the RF voltage is high. The compact cyclotron is energized by a set of superconducting coils providing the needed magnetic field, while the azimuthal varying field is done by four iron sectors. Additional superconducting coils are added to minimize the stray magnetic field, eliminating the need for a return yoke. The option of accelerating negative deuteron molecules has also been considered and is presented.

MOPPT031	SPES Project: A Neutron Rich ISOL Facility for Re-Accelerated RIBs	91

	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.
