14:00 Abstract

The design and construction of compact and lightweight gantries for hadron therapy are essential steps toward wider accessibility to this cancer treatment. GaToroid is a fixed toroidal gantry, based on superconducting magnets, able to deliver the dose at discrete number of angles with neither rotation of the magnets nor the patient. The basic principle is to use axial-symmetric magnetic field between each pair of coils constituting the torus to bend and focus accelerated particles down to the tumor. Large acceptance, steady-state configuration and superconducting magnets offer interesting reduction of size, weight and cost of gantries and related infrastructures, creating an attractive alternative to the state-of-the-art.

14:30 Abstract

While carrying out feasibility research in close collaboration with hospitals, CERN is also working on a small-scale prototype using HTS (high-temperature superconductors) technology. The practical implementation of such a cutting-edge technology requires an in-depth study of its design. Minimizing the risk of delamination and keeping all superconducting elements below their mechanical limit capacities were the main criteria for the various design choices. A careful analysis of various critical components of the scale model has been implemented. The impact of the assembly sequence on the final state of the prototype during nominal conditions was established. A rigorous justification of the design decisions will be presented here, supported by the results of the numerical simulations carried out in this framework.
