We present the results of a detailed study on the acceleration of intense ion beams by relativistic laser plasmas. The experiments were performed at the 100 TW laser at the Laboratoire pour L'Utilisation des Lasers Intenses. We investigated the dependence of the ion beams on the target conditions based on theoretical predictions by the target normal sheath acceleration mechanism. A strong dependence of the ion beam parameters on the conditions on the target rear surface was found. We succeeded in shaping the ion beam by the appropriate tailoring of the target geometry and we performed a characterization of the ion beam quality. The production of a heavy ion beam could be achieved by suppressing the amount of protons at the target surfaces. Finally, we demonstrated the use of short pulse laser driven ion beams for radiography of thick samples with high resolution.

- Ion acceleration by superintense laser-plasma interaction (2013, background): “…beam profiles even in conducting targets are surface roughness at the target rear, resulting in a randomized local orientation of the protons (Roth et al., 2002), and intensity modulations in the focal spot which can be coupled to the protons via structured electron beams in medium-Z thin…”
- Scaling of proton acceleration driven by petawatt-laser-plasma interactions (2007, result): “0p are observed and compare well with values previously reported for low repetition rate, ultraintense laser system”
