High-intensity short-pulse lasers in the Petawatt regime offer the possibility to study new compact accelerator schemes by utilizing high-density targets for the generation of energetic ion beams. The optimization of the acceleration process demands comprehensive exploration of the plasma dynamics involved, for example via optical probing. In particular, experiments using near critcal density cryogenic hydrogen jet targets with um-scale transverse size are well suited to deliver new results which can then be compared to predictive particle-in-cell simulations. We show the results of an experimental campaign at the DRACO PW laser at Helmholtz-Zentrum Dresden Rossendorf where we were able to tune the proton acceleration performance by dedicated shaping of the target density profile.
