Abstract :
High voltages and powers can be generated by turbulence in current discharges, and then transferred to electron and ion beams. These beams are the cause of large X-ray and neutron emissions, respectively. With a 340 kJ - 40 kV capacitor bank it is measured a deuteron beam of 1.2 MA - 300 keV which interacts with a 30 m diam. deuterated polyethylene target located In the plasma chamber. The experiments have been conducted in a very extended range of energy corresponding to a 100 time increase in the discharge current. With a further increase by a factor 3-10 one would reach the level requested for breakeven in Inertial confinement studies.
