Main Part of Proton Therapy Linac

The main part (MP) of a compact pulsed proton linac is designed to accelerate a beam with a pulsed current reaching 2.5 mA to an output energy controlled in the range from 60 to 230 MeV while maintaining small transverse beam dimensions. The traveling wave accelerating structure is used in the S -band frequency range. It provides a high accelerating rate and allows one to adjust the output energy of the bunches within the RF pulse. Particular attention is paid to the balance and reliability of the proposed solutions, accessibility and motivated feasibility of the MP elements.
