The influence of electrodes thicknesses on the characteristics of a helium plasma jet

Abstract An atmospheric plasma jet reactor (PJR) was designed using two outer disc-like copper plats placed around a quartz tube. The effects of the electrodes’ thicknesses and their placement on length created in helium its electrical characteristics were investigated. Measurements carried out for different applied voltages gas flow rates. (such as discharge current power consumption) obtained high voltage generator delivering sin-wave signal varying from 13kVp-p to 17kVp-p at resonance frequency 5.5kHz, measured/calculated. best results (long plume intense plasma) with equipped thicker upper electrode thinner lower electrode. Using this configuration, 55mm long reached 7slm helium.
