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.
