There is an increased interest in the generation of volume plasma at atmospheric pressure. Nonthermal volume plasmas at atmospheric pressure find applications in pollution control, sterilization, ozone generation, and surface modification. The authors studied the dielectric barrier discharge in helium and air at atmospheric pressure. Time resolved charge-coupled device camera images along with current waveforms show that a dielectric-barrier discharge can be operated in the diffused mode in a gas like helium. However, in air, the discharge consists of numerous microdischarges.
