METHOD FOR PRODUCING MULTICHANNEL DISCHARGE (ALTERNATIVES) Russian patent published in 2008 - IPC H01J13/02 H01J1/04 H05H1/34 

FIELD: plasma engineering and technology; producing multichannel discharge in large volume.

SUBSTANCE: according to first alternative method for producing multichannel discharge involving DC voltage supply between jet electrode and metal electrode, used as jet electrode is fluidic electrolyte incorporating laminar flow in top part of jet and split transient jets obtained by applying voltage of 300 ≤ U ≤ 550 V between electrodes with discharge current of 80 ≤ 1 ≤ 10 000 mA and jet laminar section diameter d_j ≤ 0.5 mm at total length of jet l = 8 - 120 mm, electrolyte discharge 2 ≤ G < 16 x 10⁶ m³/s with saturated solution of jet electrolyte and composition having atom ionization potential U_φ < 6 eVm, where U is voltage between electrodes; I is current in laminar-section electrical discharge; d_j is diameter of jet laminar section; G is electrolyte discharge. According to second alternative method for producing multichannel discharge involving voltage supply between jet electrode and second electrode, electrolytic cell is used as second electrode. According to third alternative method for producing multichannel discharge, used as second electrode is jet that constitutes angle with first one of 0 ≤ α ≤ 180°. According to fourth alternative method for producing multichannel discharge, used as second electrode is insulator with metal current lead.

EFFECT: ability of producing multichannel discharge in the course of splitting transient liquid jets in large volume.
