    "abstract": "We propose an innovative linear accelerating structure, particularly suited\nfor hadrontherapy applications. Its two main features are compactness and good\npower efficiency at low beam velocities: the first is achieved through a high\nworking frequency and a consequent high accelerating gradient, the second is\nobtained by coupling several H-mode cavities together. The structure is called\nCLUSTER, which stands for \"Coupled-cavity Linac USing Transverse Electric\nRadial field\". In order to compare the performance of this structure with other\nhadrontherapy linac designs involving high frequencies, a conceptual study has\nbeen performed for an operating frequency of 3 GHz. Moreover a proof of\nprinciple has been obtained through RF measurements on a prototype operating at\n1 GHz. An accelerator complex using a CLUSTER linac is also considered for\nprotontherapy purposes. The whole complex is called cyclinac and is composed of\na commercial cyclotron injecting the beam in a high-frequency linac.",
