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...
The accessibility of proton therapy is limited by the size and cost associated with traditional acceleration techniques. The dielectric wall accelerator (DWA) was proposed as a low-cost, compact proton accelerator capable of generating suitable beams for prot...
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...
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...
