Particle accelerators have long been perceived as large bulky machines, with the added connotations of being expensive and inaccessible. Our work strives to challenges this perception by transforming accelerator components from meter-scale metal structures to millimeter-scale dielectric devices. The potential applications of compact solid-state particle accelerators are numerous, spanning all disciplines from radiation oncology to high energy physics. In this talk, I will describe our experiments at SLAC which demonstrated acceleration gradients upwards of 300 MeV/m in a 1 millimeter long dielectric microstructure. For comparison, the acceleration gradient of the 2-mile Stanford Linear Collider was 21 MeV/m, more than an order of magnitude lower. Additionally, I will describe some very recent experiments, which highlight our progress towards creating a complete particle accelerator-on-a-chip.
Ken Soong studied physics as an undergraduate at Cornell University where he won the Kieval Prize in Physics. He received his master of science in applied physics at Stanford University and is currently completing his doctorate as a Robert Siemann Graduate Fellow, as well as a Stanford Graduate Fellow. He is currently working under Professor Robert L. Byer at both Stanford University and SLAC National Accelerator Laboratory. His research focuses on advanced accelerator concepts, specifically laser-driven particle acceleration in dielectric micro-structures. His accomplishments include the world-first demonstration of direct laser-driven acceleration and the conception of a sub-nanometer resolution beam position monitor.
