Based on needle-mesh discharge structure

design a new kind of glow discharge device

and study on influence of pin number

pin spacing

discharge spacing and carrier gas flow rate and other factors on discharge stability

threshold voltage

power and power density. Experiments show that the heat can be carried out by the carrier air

which makes the discharge more stable. The smaller the electrode spacing is

the lower the threshold voltage is

the easier the transition to spark discharge; the greater the spacing of needles is

the greater discharge power of single needle is. Energy density of discharge is not only affected by spacing of needle

but also numbers of discharge needle.
