In this work we present preliminary results of the experiments at PALS facility illustrating possibilities of magnetized plasma creation and subsequent interaction with a set of special targets. Two experimental set ups were tested experimentally, one on the basis of the 'snail' target, and the other using the so called 'open book' target, consisted of two connected plain targets. The 'snail' target is [1] was recently proposed as a optical magnetized plasma generator for the astrophysical-related studies. We expect that in the sub-relativistic regime of PALS, the magnetization of plasma in the 'snail' targets may be governed by the return current in the target, while in the case of the 'open book' it may be a combination of the fast electron and thermo-electric currents.
The experiments were performed with the 1 beam of the PALS iodine laser. In the first experiment, the'snail' targets were illuminated by the maximum achievable energy of laser beam (~ 600-700 J), at the minimum focal spot radius of about RL= 50 m. In the second experiment the two equal 1laser beams, with energy about 100-150 J each, at RL= 50-100 m, we focused on the plains of the “open book” target to create magnetized propagating plasma flows. In both experiments two kinds of targets were used: made from: Cu as 'heavy' and Al as 'light' material.
