摘要: Experimental I?V characteristics of dc microdischarges in helium at different operating pressures (p = 300?800?Torr) reveal that the classical scaling law cathode layer (sheath) does not apply. It is shown a modified semi-analytical model accounts for neutral gas heating able to reproduce trends experimental characteristics. The can also be used quantify influence on microdischarge and estimate conditions stable operation microdischarges.
