DC Glow Discharge
Model ID: 8640
DC glow discharges in the low-pressure regime have long been used for gas lasers and fluorescent lamps. DC discharges are attractive to study because the solution is time independent. The 1D and 2D models show how to use the DC Discharge interface to set up an analysis of a positive column. The discharge is sustained by emission of secondary electrons at the cathode.
