Laser-wakefield electron accelerator with independent beam-parameter control

It has been demonstrated that laser-wakefield acceleration (LWFA) can generate several electron beam parameters rivaling those generated by conventional RF-cavity accelerators. Tunable and monoenergetic electron beams have also been produced with LWFA. Currently, active research is being directed towards finding methods to generate e-beams that have independently controllable parameters, as is standard in the case of conventional accelerators. One promising approach is to separate and independently control the essential acceleration processes.
