It is often required to manipulate electron beam to match a set of parameters to a required application.  In one degree-of-freedom, bunch compression exemplifies a type of manipulation traditionally used to increase the beam’s peak current.  Within the past years, phase space manipulations aimed at manipulating the beam parameters within two degree-of-freedoms have emerged.  In this talk, I will present our work pertaining to these phase space manipulation techniques including the generation of flat beams and the transverse-to-longitudinal emittance exchange all aimed at tailoring the six dimensional phase space of the beam to a specific application.  Several applications and implementations of these techniques will be discussed, including the NIU low energy Smith-Purcell THz free-electron laser experiment, the flat beam generation at Fermilab’s ILC test accelerator and the stratus and plans of the transverse-to-longitudinal proof-of-principle experiments at the Argonne Wakefield Accelerator.
