Journal ArticleDOI
Demonstration of electron acceleration in a laser-driven dielectric microstructure
E. A. Peralta,Ken Soong,R. J. England,Eric R. Colby,Ziran Wu,Behnam Montazeri,C. McGuinness,Joshua McNeur,Kenneth J. Leedle,D.R. Walz,Esin B. Sozer,Benjamin M. Cowan,Brian T. Schwartz,Gil Travish,Robert L. Byer +14 more
TL;DR: The results set the stage for the development of future multi-staged DLA devices composed of integrated on-chip systems, and would substantially reduce the size and cost of a future collider on the multi-TeV (1012 eV) scale.
Journal ArticleDOI
Elements of a dielectric laser accelerator
Joshua McNeur,Martin Kozák,Norbert Schönenberger,Kenneth J. Leedle,Huiyang Deng,Andrew Ceballos,Heinar Hoogland,Axel Ruehl,Ingmar Hartl,Ronald Holzwarth,Olav Solgaard,James S. Harris,Robert L. Byer,Peter Hommelhoff +13 more
TL;DR: In this article, a chirped silicon grating is used to overcome the velocity dephasing of subrelativistic electrons with respect to its optical near fields, and a parabolic grating geometry serves for focusing of the electron beam.
Journal ArticleDOI
Dielectric-laser electron acceleration in a dual pillar grating with a distributed Bragg reflector
Peyman Yousefi,Norbert Schönenberger,Joshua McNeur,Martin Kozák,Uwe Niedermayer,Peter Hommelhoff +5 more
TL;DR: In this article, a distributed Bragg reflector was added to a dual pillar grating accelerating structure, which mimics a double-sided laser illumination, resulting in an enhanced longitudinal electric field while reducing the deflecting transverse effects.

TL;DR: This Letter shows how lithographically produced nano-structures help to make novel laser accelerators more efficient.
Journal ArticleDOI
Transverse and longitudinal characterization of electron beams using interaction with optical near-fields.
Martin Kozák,Joshua McNeur,Kenneth J. Leedle,Huiyang Deng,Norbert Schönenberger,Axel Ruehl,Ingmar Hartl,Heinar Hoogland,Ronald Holzwarth,James S. Harris,Robert L. Byer,Peter Hommelhoff +11 more
TL;DR: The synchronous accelerating/decelerating fields confined to the surface of a silicon nanostructure are characterized using a highly focused sub-relativistic electron beam to demonstrate transverse and longitudinal characterization of bunched femtosecond free electron beams.
