The design characteristics and parameters of a compact cyclotron able to accelerate H− ions up to an energy of 35 MeV and H2+ ions up to an energy of 8 AMeV are presented. This cyclotron is a 4 sector machine and its special feature is the possibility to modify the profiles of the sector hills to allow for the acceleration of the two different species. When equipped with two RF cavities and operated in harmonic mode 4, it accelerates the H− beam, which is extracted by stripping. The resulting proton beam is used for the commercial goal of radioisotope production. On the other hand, when equipped with four RF cavities, also operated in harmonic mode 4, it accelerates a high intensity H2+ beam that is of interest for the IsoDAR* experiment. Here, the presented cyclotron takes on the role of a prototype for the central region design of the final IsoDAR* cyclotron (60 A MeV H2+). By increasing the number of cavities, the energy gain per turn as well as the vertical focusing along the first orbit are increased, thereby optimizing the acceptance. Moreover, to minimize space-charge effects, the injection energy of H2+ is raised to 70 keV compared to the H− injection energy of 40 keV.

| THPF037 | Upgrade of the LNS Superconducting Cyclotron | 3779 |
|

| The superconducting cyclotron of the LNS-INFN has been working for about 20 years delivering ion beams from proton to gold in the wide energy range from 15 AMeV to 80 AMeV. The beam extraction is performed by means of two electrostatic deflectors and a set of magnetic channels. Recently, the experiment NUMEN has been proposed to study the nuclear matrix element for the double beta decay . The requirements on target are light ion beams (A<30), with an energy range of 15-60 AMeV and a beam power of 1-5 kW. To achieve this goal we have studied the feasibility of extraction by stripping through the existing extraction channel with an increased transversal section. In addition, a new extraction channel has been designed to increase as much as possible the number of the extracted ions and energies. To allow the realization of these new channels, a new superconducting magnet is needed. The major changes and the expected performances for the upgraded cyclotron, as well as the state-of-art of the design, are here presented. | ||
