Bunch Shaping in Electron Linear Accelerators
G. Ha, K.-J. Kim, P. Piot, J.G. Power, Y. Sun

     Modern electron linear accelerators are often designed to produce 
smooth bunch distributions characterized by their macroscopic 
ensemble-average moments. However, an increasing number of accelerator 
applications call for finer control over the beam distribution, e.g., by 
requiring specific shapes for its projection along one coordinate. 
Ultimately, the control of the beam distribution at the single-particle 
level could enable new opportunities in accelerator science. This review 
discusses the recent progress toward controlling electron beam 
distributions on the "mesoscopic" scale with an emphasis on shaping the 
beam or introducing complex correlations required for some applications. 
This review emphasizes experimental and theoretical developments of 
electron-bunch shaping methods based on bounded external electromagnetic 
fields or via interactions with the self-generated velocity and 
radiation fields.
