“…The gantry proposed in this study is designed to deliver a beam from a linear accelerator. In the past few years, the CERN spin-off company ADAM (Application of Detector and Accelerators to Medicine) has developed a prototype for the LIGHT accelerator -the first commercial linac for proton therapy [13]. Its features make it well suited for the active spot scanning technique.…”

“…The intrinsic lower weight of the magnets reduces the weight of the gantry by one or two orders of magnitude with respect to conventional gantries in operation. For the required field gradients and apertures of about 3 cm diameter, the predicted outer diameter of the magnets is approximately 8 cm (13). The lighter compo-nents should also reduce the cost of the rotating structure.…”

This report presents a design of a gantry for proton therapy based on the concept of adiabatic transition. The use of fixed-field alternating gradient magnets allows a large momentum acceptance and supports fast energy modulation. The optical performance of the gantry has been analysed using a beam tracking code. Several optimisations of the lattice and transition sections have been investigated to reduce size and ensure applicability to pencil beam scanning. Matching of the full energy range results in an increase in the size of the gantry, but reduces the weight and cost significantly compared to those that pertain to facilities in operation.

High-frequency linear accelerators are very suitable for carbon ion therapy, thanks to the reduced operational costs and the high beam quality with respect to synchrotrons, which are presently the only available technology for this application. In the framework of the development of a new linac for carbon ion therapy, this article describes the design of a compact 750 MHz Radio Frequency Quadrupole (RFQ) with trapezoidal vanes. A new semi-analytic approach to design the trapezoidalvane RFQ is introduced together with the relevant beam dynamics properties. The RFQ is split into two decoupled rf cavities, both of which make use of a novel dipole detuning technique by means of length adjustment. The splitting is described both from the rf and the beam dynamics point of view. The paper concludes with the rf design of the full structure, including maximum surface field and thermal studies.
