Experiments on generation of High Power Ion Beam in plasma-filled diode

Abstract

The experimental results on High Power Ion Beams (HPIB) generation in plasma-filled spherical focusing diode with self magnetic insulation, which was placed for a load at nanosecond accelerator PARUS of 0.2 TW power and 60 ns pulse duration (in matched load case) are given. The regimes of plasma-filled diode operation and generation of ion beam were investigated. For optimal time delay-between the plasma guns pulse and accelerator firing the stable operation in the plasma opening switch mode with power enhancement factor of 2.3 and efficiency of ion beam generation of 20-25% was obtained. The maximal value of the ion current density in the focal plane was reached 15 kA/cm2.
