Momentum Acceptance

In proton therapy, the last part of the beam transport system is installed on a rotatable gantry, so that the beam can be aimed at the tumor from different angles. Since such a gantry system consists of many dipole and quadrupole magnets, it is typically a 100–200 tons device of more than 10 m in diameter. The use of superconducting (SC) magnets for proton therapy allows gantries to be significantly lighter and potentially smaller, which is attractive for this medical application. In addition to that, SC combined function magnets enable beam optics with a very large momentum acceptance. The latter can be advantageous for patient treatment, since the irradiation time can then be significantly reduced by avoiding magnet current changes. To design such an achromatic system, we performed precise high-order calculations. To reach the required accuracy and to check consistency of the obtained results, we have used different simulation tools in our iterative design approach. Here, we will describe our beam optics calculations in the code COSY Infinity and particle tracking using OPAL (open source software from PSI) in 3D field maps obtained from detailed magnet calculations performed in Opera. Our method has shown to be advantageous in a complicated beam optics study and it reduces the risk of systematic errors in a design.

Due to the unique “Bragg peak” dose-distribution characteristics of proton beams, the proton therapy (PT) is recognized as one of the most precise and effective radiotherapy methods for tumors. A gantry is required to project the beam onto a tumor at various angles for multiple-field irradiation, and a superconducting beamline can significantly reduce the size and weight of the gantry. A PT system is under development at Huazhong University of Science and Technology (HUST), and this paper presents a comparison study of the beam optics and related design considerations for normal conducting and superconducting gantry beamlines.
