A method of plasma treatment of an internal and/or external surface of a hollow electrically non-conductive body. The internal surface of the body and/or its external surface acts a layer of electrical plasma of a surface dielectric barrier discharge generated in a volume of gas by alternating or pulse voltage with an amplitude higher than 100 V from a pair of liquid electrodes formed by an internal electrically conductive liquid situated inside the body and by an external electrically conductive liquid situated outside the body. The electrical plasma is generated above the surface of the electrically conductive liquid, where in the volume of the gas forms a layer of electrical plasma forming a ring copying the shape of the surface of the body wherein the electrical resistance between the liquid electrodes is greater than 10 k&#x3a9;. The invention also is a device for carrying out the aforementioned method.

A method for reducing or removing organic and/or inorganic contamination from a vacuum system of imaging and analytical devices, wherein at least a portion of the area of the inner surface of the vacuum space of the vacuum system is provided with a photocatalytic layer, at least a portion of this photocatalytic layer being cooled to a temperature in the range of 0 K to 280 K, whereby the photocatalytic layer is afterwards at least partially irradiated by electromagnetic radiation, which activates a photocatalytic reaction of the photocatalytic layer with the adsorbed gases of the atmosphere of the inner vacuum space of the vacuum system, where this reaction decomposes the contaminants, reducing their concentration and/or the concentration of water in the inner vacuum space of the vacuum system.
