Beschreibung

We report results on all-optical Thomson scattering within a laser wakefield accelerator. We show that the pulse collision can be detected using transverse shadowgraphy, facilitating alignment and permitting accurate determination of the scattering position. As the electron beam energy is evolving inside the accelerator, the emitted spectrum changes with the scattering position. Such a configuration could be employed as accelerator diagnostic as well as reliable setup to generate X-rays with tunable energy. Furthermore we report results on multi-energy X-ray imaging using a single beam setup with a plasma mirror and tunable shock-front injected electrons.
