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.
