Observations n Microbunching of electrons in Laser-Driven Plasma Accelerators and Free-Electron
Abstract
We provide observations on the visible-wavelength microbunching of relativistic electrons at beam energies >200 MeV in both laser-driven plasma accelerators (LPAs) and a self-amplified spontaneous emission (SASE) free-electron laser (FEL). An analytical model for coherent optical transition radiation interferometry (COTRI) addresses both cases. It is noted that the COTR/OTR gain observed in the LPA rivals that of the SASE FEL at saturation, although the few micron transverse sizes of the microbunched beamlets are much smaller than in the FEL. The broadband microbunching observed in the LPA case could act as a seed for a SASE FEL experiment with tunability over the visible regime, in principle.
