Abstract

A protons and light carbon ions accelerator finalized to the therapy of deep tumors is in construction under the responsibility of the CNAO (National Center for Oncological Hadrontherapy) and INFN in Pavia (Italy). The feasibility study of the ramping Power Supply (3000 A-1600 V, 1.6 s cycle, maximum current error 30 mA) for the synchrotron bending dipoles is described in this paper. Suitable topology analysis, feedback control design and simulation results are presented
