This invited talk presents the most important results of theoretical and experimental studies of high-current Plasma-Focus (PF) discharges, as performed recently in a frame of the scientific collaboration of IPJ and IPPLM, Poland. Progress in studies of the breakdown and axial acceleration phase was achieved. Numerical computations showed that a modified MHD model is satisfactory until the maximum compression. In experimental studies the use was made of different diagnostic techniques. Correlations of X-ray pulses with other PF phenomena were analyzed, and differences in polarization of X-ray spectral lines were explained. Fast electronbeams (emitted through the axial channel) were analyzed, and energetic ions (emitted in the forward direction) were measured. Anisotropy of fusion neutrons was investigated and its temporal changes were analyzed. For the first time an optical spectrometer with a high temporal resolution was applied to study the evolution of spectral lines. The main issues of PF studies were also considered.
