CERN has a long-standing tradition of fostering collaborations with leading facilities in cancer research and treatment for the development of radiotherapy and ion-therapy infrastructures based on CERN technology. In 2020, CERN signed three new agreements with CNAO, the National Center for Oncological Hadrontherapy (Italy) and with EBG-MedAustron, the company responsible for the construction and operation of MedAustron cancer treatment and research centre (Austria). CERN will support CNAO in the development of a new electrostatic septum, used to extract beam from their synchrotron; and collaborate with EBG-MedAustron on the development of their beam extraction infrastructure and magnet measurement techniques. In addition, a collaboration with the Centre for Energy, Environment and Technology (CIEMAT) was initiated to construct an injector for an ion therapy linear accelerator.
