Description
Hard x-ray/gamma-ray emission from laser wakefield accelerator have a number of interesting applications, e.g. ultrafast dynamic probing of matter. Betatron radiation and Thomson scattering are highly collimated laser-driven hard x-ray/gamma-ray sources with fs duration which generated by electron transversely oscillation in wakefield or laser field. However, photon yield is always limited by electron charge which is controlled by beamloading effects during acceleration. So, we proposed several experiments to increase accelerated electron charge, such as double injection, ps laser driven, NCD targets etc. As a result, greatly improved radiation sources are archived in our experiments.
