  The LIGHT project is a collaboration of several laser and accelerator laboratories in Germany with the purpose to consolidate the theoretical, numerical and experimental investigations for the usage of laser accelerated ions in the conventional accelerators. The central facility is the PHELIX laser at GSI, Darmstadt, with a strong-field solenoid as a collimation and transport device. This contribution is devoted to the numerical investigation of the proton acceleration via the TNSA mechanism using 1D and 2D particle-in-cell electro-magnetic simulations. The phase-space distribution of the accelerated protons and co-moving electrons, which is necessary for further transport studies, is investigated for different parameters of the thin hydrogen-rich contamination layer on the rear target surface. Depending on the layer thickness the protons can be accelerated in different regimes, from the quasi-static acceleration for mono-layers up to the isothermal plasma expansion for thick layers.
