This invited lecture presents author’s comments on results of the experimental studies of dense and high-temperature plasmas, which were carried out in Poland during recent two years. Those studies were performed with the PF-360U device at NCBJ, and the PF-1000U facility at IFPiLM. There were investigated fast electron beams and soft x-rays, an influence of thin metal wires and/or an admixture of heavier gases, an influence of a shape of the anode end, as well as plasma micro-structures in a pinch column, i.e. plasma filaments and hot-spots (of electron densities > 10¹⁹ cm⁻³ and electron temperatures ranging several keV). The detailed studies concerned also the VR and x-ray emissions, estimates of local electron temperatures, and fast deuteron beams. Other experiments were devoted to investigation of plasma jets which can have dimensionless parameters corresponding to astrophysical objects. There are also presented some examples of the technological applications of PF discharges, studied in a frame of the Polish-Ukrainian scientific collaboration. The author’s comments are followed by proposals of some future theoretical and experimental studies.
