Design, construction and tests of a 3 GHz proton linac booster (LIBO) for cancer therapy
A prototype module of LIBO has been built and successfully tested with full RF power at CERN and with proton beam at INFN Laboratori Nazionali del Sud (LNS) in Catania, within an international collaboration between TERA Foundation, CERN, the Universities and INFN groups of Milan and Naples.
As a consequence of these tests we prove, for the first time, that it is possible to inject and accelerate proton beams from a cyclotron into a 3 GHz linear accelerator. The prototype construction proves also that standard technology can be adopted for fabrication, covering at the same time the stringent physical performances of a compact linac for hadrontherapy. A final accelerating gradient of 29 MV/m has been then reached, so even better than the design value of 15.3 MV/m. The mid-term aim of the project is the technology transfer of the accumulated know-how to a consortium of companies and to bring this novel medical tool to hospitals. The design, construction and tests of the LIBO prototype are described in detail.
