Variation of charge in acoustoplasma during the period of modulation of the discharge current

We investigate dynamic parameters of acoustoplasmic discharge associated with the time variation of concentration of charge carriers. Instantaneous values of the difference in currents measured by the anode and cathode are determined depending on the frequency of modulation of the discharge current. The volt-coulomb characteristics of acoustoplasmic discharge are also measured. The observed jump of the charge at gradual variation of the voltage on the discharge tube can be considered as a phase transition in acoustoplasma.
