FIELD: plasma technologies. ^ SUBSTANCE: device has two electrodes, dielectric blocks, made of special material, discharge channel with open end portion, walls of which are formed by surfaces of electrodes and dielectric blocks, energy accumulator, current feeds, connecting electrodes to energy accumulator, which together with electrodes and accumulator form an external electric circuit, isolator, mounted between electrodes near end portion of discharge channel, opposite to open end portion, and charge initiation device. Characteristics of external electrical circuit of accelerator are selected from condition : 2<=C/L, where C - electric capacity of external electric circuit in micro-farads, and L - inductiveness of external electric circuit in nh, value of which satisfies the condition: L<=100 nh. Plasma acceleration method includes ignition of charge in discharge channel of plasma accelerator in pulse feed of discharge voltage from energy accumulator to electrodes of plasma accelerator. In discharge channel of accelerator quasi-periodic pulse discharges are ignited and maintained with value of discharge voltage U no less than 1000 volts and above-mentioned characteristics of accelerator electric circuit. ^ EFFECT: higher efficiency. ^ 2 cl, 9 dwg |
