Abstract
The design of future linear colliders is highly constrained by their cost and footprint. Phase space partitioning offers an attractive path towards cost and complexity reduction through precise tailoring of particle beam distributions. In this dissertation, we discuss a phase space manipulation technique for generating flat electron beams---a type of beam distribution of particular interest to linear colliders. We report the experimental generation of flat beams with transverse-emittance ratio up to 200 at Argonne Wakefield Accelerator facility. We further expand the technique by combining it with transverse-to-longitudinal emittance exchange. We present the conceptual design of an electron injector capable of delivering flat electron beams with phase-space partition comparable to the electron-beam parameters produced downstream of the damping rings. In addition, we describe a laser shaping technique that supports the generation of ramped electron bunch distribution. Such beam distribution is expected to significantly improve the energy gain in collinear wakefield accelerators.
