A novel inertial fusion concept (by Marvel Fusion) proposes the use of nanostructured targets in the form of arrays of thin rods that are irradiated by high-intensity laser pulses. The resulting interaction potentially enables heating and compression of mixed solid fusion fuels. Experimental validation of this approach is crucial, but the underlying dynamics unfold on femtosecond time scales and nanometer length scales, posing significant diagnostic challenges. In the framework of the VANLIFE collaboration, this work investigates the feasibility of probing nanostructured targets during the laser-target interaction using laser-driven plasma-wakefield accelerators for X-ray generation, delivering ultrashort and high-brightness pulses via Betatron radiation. We want to explore possibilities to use these radiation sources to probe the interaction at such nano targets and gain a better understanding of diagnostic challenges in probing rapidly expanding, high-density laser-plasma interactions.
