Spatial and temporal electron beam manipulation with dielectric laser accelerators
Abstract/Contents
- Abstract
- Particle accelerators are an indispensable tool of modern physics. However, high-energy particle accelerators tend to have sizes ranging from large buildings to small cities, which limits their utility. Dielectric Laser Accelerators (DLAs) use pulsed lasers to increase the "acceleration gradient" tenfold over conventional accelerators. This allows them to be made many times smaller, and to be nanofabricated at scale on silicon wafers. This dissertation will present the techniques developed for manipulation of electron beams in DLAs, including demonstrations of three key accelerator subunits: a laser-driven magnetic lens for beam confinement; a two-stage ballistic microbunching scheme; and a streak camera capable of attosecond resolution for beam diagnostics. By combining these subunits, a working prototype of a DLA-based injector is demonstrated for future on-chip high-energy beamlines. In the first chapter, the two-dimensional theory of DLA operation is derived in its full generality. Next, strong, laser-driven spatial focusing of an electron beam is demonstrated, sufficient to confine the electron beam within the DLA channel. Third, I investigate the manipulation of longitudinal beam structure by a ballistic microbunching scheme, and demonstrate attosecond-scale control over microbunch formation using a two-stage DLA. This allows demonstration of the net acceleration of a microbunched pulse train. Finally, by combining the two-stage longitudinal bunch manipulation techniques with the laser-driven DLA lens, I am able to demonstrate the creation and coherent acceleration of low energy spread microbunched pulse trains, which constitutes a fully functional prototype of a DLA injector.
