Anomalous ions acceleration in the double-pulse setup

Mass-charge spectra and energy distributions of anomalous accelerated ions were obtained in the double-pulse setup. In the setup the plasma cloud of the 30 kV vacuum flashover interacted with the plasma flare of the 300 kV vacuum spark discharge. The plasma cloud ions appeared in the ion flow. The energies of these ions are much more than 30 keV that could be attained in the flashover discharge alone. The energy peaks in these distributions can be associated with the voltage values at the moments of the current instabilities.
