TI - Upgrade of the LNS Superconducting Cyclotron J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - 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.
