Beam manipulation and acceleration with dielectric-lined waveguides

摘要

The development of next-generation TeV+ electron accelerators will require either immense footprints based on conventional acceleration techniques or the development of new higher--gradient acceleration methods. One possible alternative is beam-driven acceleration in a high-impedance medium such as a dielectric-lined-waveguide (DLW), where a high-charge bunch passes through a DLW and can excite gradients on the order of GV/m. An important characteristic of this acceleration class is the transformer ratio which characterizes the energy transfer of the scheme. This dissertation discusses alternative methods to improve the transformer ratio for beam-driven acceleration and also considers the use of DLWs for beam manipulation at low energy.
