Abstract
We present recent experiments on the characterization of Betatron radiation in the blowout regime of laser-wakefield acceleration. We observed Betatron x-rays up to 80 keV, and the characterization of the angular dependence of the x-ray spectrum suggests anisotropic electron trajectories in the plasma. The characterization of the source opens up new possibilities for application experiments.
