Laser wakefield accelerators can provide a very compact source of electron beams, which when combined with intense laser pulses result in a versatile X-ray source. Of particular interest for medical imaging are X-rays in the 50-100 keV energy range, high enough energy to penetrate through human-sized objects. Such beams also form the basis of an all optical Thomson source for X-ray Fluorescence Imaging (XFI) of (functionalized) gold-nanoparticles (F. Grüner et al., Sci. Rep. 8, 16561 (2018)). Experimental progress towards realising such a source for XFI with gold nanoparticles is presented, with simulation studies of using an active plasma lens to restrict the radiation spectrum detailed.
