 note = {In the last two decades the regime of ultraintense (>10^19 Wcm-2) laser pulses producing and interacting with plasma has revealed unprecedented advancements in particle accelerations and as a secondary source of high-energy radiation beams.
Previous experiments, developed in our group, have discovered coherent x-ray beams with high brightness (approaching that of FELs) and composed of multiple high order harmonics. The following experiments and simulations have shown that the produced x-ray sources are from tens to hundreds of nanometers in size. This novel phenomenon is known as BISER.
Here, we report new experimental results concerning spatial distribution of these promising x-ray sources, which will enable a more rigorous understanding of the underpinning physics of its origin and the effect of specific laser parameters on its spatial pattern and brightness.
