Highly spatially and spectrally resolved X-ray emission from the laserdeflected part of the warm dense Cu foil visualized the hot electrons. A multi-scale twodimensional hydrodynamic simulation including non-linear laser-plasma interactions and hot electron propagation has provided an input for ab initio non-thermal atomic simulations. The analysis revealed a significant delay between the maximum of laser pulse and presence of suprathermal electrons. Agreement between spectroscopic signatures and simulations demonstrates that combination of advanced high-resolution X-ray spectroscopy and nonthermal atomic physics offers a promising method to characterize suprathermal electrons inside the solid density matter.
