Abstract
A non-thermal plasma or corona discharge is generated at multiple points and distributed to decontaminate surfaces and objects contaminated with chemical or biological agents. The corona discharge can be generated using very short high voltage pulses. The pulsed corona discharge can be directed at a contaminated surface through the unbraided strands at an end of a dielectric covered conductor. Another pulsed discharge embodiment incorporates a primary coil surrounding a chamber having a void filled with a plurality of secondary coils. A silent corona discharge can be generated using a variety of different configurations of a dielectric coated electrode and a bare electrode. The silent discharge is produced at all intersections between the dielectric covered electrode and the bare electrode. In one embodiment the apparatus comprises a blanket-like structure that is useful for decontaminating surfaces or decontaminating a fluid passing between spaced-apart bare electrodes.
