AB  - The combination of laser-wakefield acceleration and Thomsonscattering (TS) driven by one high-power laser allows for all-opticalbrilliant X-ray sources of compact design. Such source designs enablethe clinical implementation of X-ray-based medical imaging modalitiessuch as X-ray fluorescence imaging (XFI). XFI offers the in-vivolocalization of functionalized gold nanoparticles (GNPs) with highsensitivity, temporal and spatial resolution at low dose exposure. Thisrequires hard X-ray sources ( 100 keV) of specific design parameters,i.e. a pencil-shaped X-ray beam within a small bandwidth and a highphoton flux to achieve feasible exposure times. Thus, optimization ofthe TS process is required to enhance the X-ray source to fulfill thegiven criteria. In this poster we show the techniques employed for thedetermination of the best laser and electron parameters. The designconcept and simulation results for a first proof-of-principle experimentare presented. Electron focusing via an active plasma lens allows forsingle-element symmetric focusing on the one hand. On the other handX-ray bandwidth control for broadband electron energy spectra (no energyspread limit) is achieved.
