Abstract :
A new mechanism of the collective acceleration of ions at the spark stage of a vacuum discharge is proposed. It has been show n that this acceleration can take place in the presence of a plasma cloud in the electrode gap with strong electronic instability developing in the plasma. The appearance of accelerated ions of the interelectrode plasma is accompanied by a jump in the diode current.
