Investigation of betatron radiation from laser-wakefield accelerators

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.
The experiments are carried out with the Draco Ti:Sapphire laser system at HZDR.
