Description
Betatron radiation emitted by accelerated electrons in laser-wakefield accelerators can be used as a diagnostic
tool to investigate electron dynamics during the acceleration process. Utilizing a 2D X-ray imaging spectroscopy
technique we analyse the spectral dependence of the emitted Betatron pattern which basically represents certain
electron beam parameters inside the plasma cavity. We also compare to the case when electrons are intentionally
injected off-axis by introducing a pulse front tilt on the driver laser beam. The experiments are carried out
with the Draco Ti:Sapphire laser sytem at HZDR.
