Description
The University of Melbourne’s TURBO (Technology for Ultra Rapid Beam Operation) project aims to improve charged particle therapy by developing large momentum acceptance beamlines to reduce the energy layer switching time, increasing the efficiency of delivery systems for cancer treatment. Previously, a closed-dispersion arc has been designed utilizing non-linear magnets built as Halbach arrays, which achieves up to ±42% rigidity acceptance in a beamline with an overall bend of 30°. Here – considering the technological complexity of these non-linear magnet arrays – we present a design methodology for compact large momentum acceptance beamlines based on separate-function magnets. We find parameters representing clinical beam quality requirements and perform a multi-objective optimization to investigate trade-offs between them. The separate-function approach provides an alternative for a full-scale beamline that relies on simpler, commercially available technology.
