Short-length arcs between copper electrodes_Fig.5

Predicted properties as a function of the field enhancement factor and a current Density of 4.8e5 A/m^2 in pure argon.
a) Tc - temperature on the cathode; j_TF - current density caused by themo-field electron emission
b) In the middle of the gap: T - temperature of heavy particles, Te - electron temperature, ne - electron density;
c) Uarc - discharge voltage.
Additionally available: Ta -temperature on the anode.
