  The MedAustron Particle Therapy Accelerator located in Austria, delivers proton beams in the energy range 60-250 MeV/n and carbon ions 120-400 MeV/n for medical treatment in two irradiation rooms, clinically used for tumor therapy. Proton beams up to 800 MeV/n are also provided to a room dedicated to scientific research. Over the last two years, in parallel to clinical operations, we have completed the installation and commissioning of the gantry beam line in a dedicated room, ready for the first patient treatment in early 2022. In this manuscript, we provide an overview of the MedAustron gantry beam commissioning including the world-wide first ’rotator’ system, a rotating beamline located upstream of the gantry and used to match the slowly extracted non-symmetric beams into the coordinate system of the gantry. Using the rotator, all beam parameters at the location of the patient become independent of the gantry rotation angle. Furthermore, both the gantry and the high energy transfer line optics had to be redesigned and adapted to the rotator-mode of operation. A review of the beam commissioning including technical solutions, main results and reference measurements is presented.

The Heavy Ion Therapy Research Integration plus (HITRIplus) is a European project that aims to integrate and propel research and technologies related to cancer treatment with heavy ions beams. Among the ambitious goals of the project, a specific work package includes the design of a gantry for carbon ions, based on superconducting magnets. The first milestone to achieve is the choice of the fundamental gantry parameters, namely the beam optics layout, the superconducting magnet technology, and the main user requirements. Starting from a reference 3T design, the collaboration widely explored dozens of possible gantry configurations at 4T, aiming to find the best compromise in terms of footprint, capital cost, and required R&D. We present here a summary of these configurations, underlying the initial correlation between the beam optics, the mechanics, and the main superconducting dipoles design: the bending field (up to 4 T), combined function features (integrated quadrupole), magnet aperture (up to 90 mm), and angular length (30°-45°). The resulting main parameters are then listed, compared, and used to drive the choice of the best gantry layout to be developed in HITRIplus.
