TI - Rapid RF-Driven 3D Pencil Beam Scanning for Proton Therapy J2 - Proc. of IPAC2022, Bangkok, Thailand, 12-17 June 2022 CY - Bangkok, Thailand T2 - International Particle Accelerator Conference T3 - 13 LA - english AB - We report on the development of a 2.856 GHz accelerator system to provide energy modulation and RF-based steering for rapid 3-D beam scanning for proton therapy. Designs for the accelerator and deflector cavities have been modeled in ANSYS-HFSS and used to produce prototype structures. We present high power test results for a single cell energy modulator prototype and a three cell deflector prototype. Using General Particle Tracer, we simulate proton beam transport through the fully rendered accelerator and deflector beamline. System performance is optimized for the case of sub-relativistic protons with 230 MeV kinetic energy and covers an energy modulation range of ±30 MeV. We present simulated beam profile data after energy modulation and lateral steering, achieved using a combination of dynamic RF deflector cavities and static permanent magnet quadrupoles.
