FIELD: measurement technology.

SUBSTANCE: method of determining values of parameters of a discharge circuit with a capacitive energy accumulator loaded on a gas-discharge interelectrode gap, which provide maximum energy efficiency of producing nanoparticles in a pulsed gas discharge. Method is based on experiment with test capacitance accumulator, in which pulse current and voltage are measured, by means of which circuit parameters are calculated – equivalent value of active electrical resistance, equivalent value of inductance of discharge circuit and value of amplitude of interelectrode voltage for used electrodes. According to these data, using minimum interelectrode gap, at which transfer of electrode material to the opposite electrode is excluded and surface roughness of electrodes does not affect stability of interelectrode gas breakdown, optimum value of capacitance of energy accumulator loaded to gas-discharge interelectrode gap is calculated. Method is realized using a model of a pulse gas-discharge generator with copper electrodes and current and voltage meters designed for this purpose.

EFFECT: higher electrical efficiency of devices for producing nanoparticles in pulsed gas discharge by means of electric erosion of electrodes, including from metals, alloys and semiconductors.
