Investigation of Micro-Scale Laser-Powered Dielectric Particle-Accelerators with Potential Application in the Long Range Sensing of Fissile Material Grant

Abstract

Advanced accelerators have been proposed to increase by orders of magnitude over conventional approaches the energy gained per unit distance, or gradient, in charged particle beams. The higher the gradient an accelerating structure can support and be powered to, the shorter length of device needed to reach a particular energy. These advanced accelerator schemes therefore promise to reduce the size (and cost) of major scientific instruments and medical and industrial systems. Dielectric Laser Accelerators (DLAs) are a class of advanced accelerators that use optical-scale structures powered by lasers to achieve these high gradients. We report on the first demonstration of acceleration within a resonant DLA. The structure required complex modeling and fabrication methods to realize the results the results here serve as a proof of principle and confirmation of the physics and technical ability underlying this approach to acceleration, and open the possibility of bread-box sized light sources.
