Canted Cosine Theta (CCT) magnet is a very interesting design for compact accelerators or gantry systems for hadron-therapy. Indeed, it offers great flexibility in generating complex field harmonics in straight and curved configurations for which compactness is even higher. The Fusillo project at CERN aims to design, build, and test a Nb-Ti curved CCT dipole demonstrator generating 3 T at 4.5...
Lanzhou Ion Therapy Company, Ltd. (LANITH) began the research and development of miniaturized heavy ion therapy devices since 2022. The Gantry superconducting magnet, which composed of a curved dipole magnet and two quadrupole magnets at both ends of the dipole coil, is the core component of the whole device. At present, this project has completed manufacturing process for a prototype and a...
The European I.FAST project’s WP8 initiative focuses on advancing Canted Cosine Theta (CCT) magnet technology using High-Temperature Superconductors (HTS). These magnets aim to revolutionize synchrotron and gantry designs by reducing their size and cost, offering transformative potential for research and hadron therapy. HTS materials enable higher magnetic fields and smaller cryogenic systems...
The treatment of cancers with particles is a superior modality compared to a treatment with X-rays. Particles are more effective and treatment is more localized, thereby sparing healthy tissues and reducing the risk of secondary tumors, resulting in an improved quality of life, as well as being the only radiation option for children and infants. Despite the clear advantages of particle therapy...
Superconducting gantries are required to reduce the size and cost of proton or carbon beam delivery systems for cancer radiation treatment. To map out the whole volume of a tumor, a well-focused pencil beam is scanned over the tumor in the two transverse directions while beam penetration and energy deposition in the axial direction is achieved by adjusting the beam energy. To minimize the...
Halbach dipole cylindrical magnets have attracted significant attention due to their ability to generate high magnetic flux density within limited space. However, the end-effect significantly impacts the uniformity of the magnetic field, hindering the application of Halbach dipole arrays, especially in low-field MRI. Currently, most optimization methods focus on adjusting the geometric...
