<p>A non-thermal plasma cell comprising an annulus 2 of a dielectric material, such as ceramic, formed from a continuous wall of material. The continuous wall having a plurality of apertures 10 therein and a pair of annular air-permeable electrodes mounted on opposing sides of the wall of the dielectric. Optionally an air gap is provided between each electrode and the wall over at a least part of the circumference of the wall. The thickness of the dielectric material is substantially greater than the thickness of the electrodes, which may comprise metal foils. This is primarily used as a filtering means in decontamination devices.</p> |
