The dielectric wall accelerator (DWA) offers a low-cost solution for proton therapy with non-resonant waveguides. Radial waveguides (RWGs) transport electronically-switched nanosecond pulses and produce an accelerating electric field in the beam pipe. Previou...

Effect of Varying Lateral Spot Size and Beam Energy Spread on Proton Therapy Treatment Plans
Proton therapy (PT) has demonstrated superior healthy tissue sparing compared to photon radiotherapy for various sites; however, PT systems are expensive, which limits global availability. The dielectric wall accelerator (DWA) is proposed as a low-cost, compa...

Optimizing the Wall Thickness of a Rexolite Beam Pipe Towards a Proof of Concept Dielectric Wall Accelerator
To investigate the optimal wall thickness for a Rexolite beam pipe for a proof-of-concept dielectric wall accelerator (DWA). In a DWA, protons are accelerated by a virtual traveling wave, created by switching electric fields along a dielectric beam pipe. The...
