Conceptual layout for a wafer-scale dielectric laser accelerator

Acceleration of particles in laser-driven dielectric structures fabricated using semiconductor manufacturing techniques is a new and promising approach to developing future generations of ultra-compact particle accelerators. We present a conceptual layout for a wafer scale device based on this approach. We examine one particularly promising near-term use for such accelerators in radiation oncology, and discuss energy scaling for high energy physics and basic energy science applications.
