The paper describes experimental studies of x-ray pulses generated by implosions of current-sheaths onto sufficiently thick carbon fibers with the focus on a possibility of pumping the inverse population of hydrogen like ions levels. The stabilizing role of carbon fibers on the pinched-phase plasma is suggested and documented by the pinhole and streak camera pictures, PIN diode signals, and detected non-equilibrium spectrum of the Lyman lines of hydrogen-like carbon ions

The processes in the magnetized plasma are influenced by spontaneous generated internal magnetic fields and induced currents. In the plasma with high density of particles convenient for ICF we can observe very fast energy transformation in range of ps or ns. In that plasma the high energy electrons and ions occur. Problem of their acceleration is under discussion. One possible mechanism is based on the transformation and dissipation of internal magnetic field. In this case the reconnection of magnetic lines can play an important role. This problem is studied for example in solar flares as well. In this paper we present results of the development of the discharge with distance of electrodes 40 cm, current of 300 A and duration in order of 100 ms. Its behavior is directed by magnetohydrodynamic phenomenon – pinching, development of helical instabilities, connection of two channels with opposite orientation of the electric current, forming of the loops, squirm of the loops and forming and disintegration of spherical forms of the squirmed loops.

The paper reports on measurements of pulsed high energy electrons formed by the PF 1000 device, operated at IPPLM in Warsaw, Poland. This plasma focus device is used as powerful pulse sources of particles and X-rays. When deuterium is used as a filling gas, fast neutrons originating from D-D fusion reactions can be also observed. To measure the electrons, X-rays and neutrons, we used different time- resolved diagnostics techniques, e.g. Cherenkov detectors, X-ray pinhole camera, visual quadro and streak cameras and different scintillation detectors for X- ray and neutrons. The correlations between obtained pulses and other investigated plasma - focus phenomena are discussed.
