An apparatus with a narrow slit chamber generates plasma having non-equilibrium characteristics and a brush-like shape at a temperature near room temperature and at a pressure of about one atmosphere. Plasma gas enters the narrow slit chamber. An external power source provides power to electrodes near the exit that excite the plasma gas and produce a plasma jet having a brush-like shape that exits the chamber. The apparatus operates with low power consumption, and the temperature of the plasma is low. Glow-to-arc transitions are prevented using a ballast resistor and appropriate plasma gases with the narrow slit chamber design. The brush-like shaped plasma extends beyond the exit of the chamber, and possesses the reactive features of low-pressure or non-equilibrium plasmas. The plasma brush apparatus can be used for plasma treatment, plasma cleaning, plasma deposition, plasma sterilization, and plasma decontamination of chemical and biological warfare agents.
