Method for the creation of ultraviolet radiation from a microwave source and device for implementing this method

摘要

The invention relates to a method for the creation of ultraviolet radiation from a microwave source and from an electrode-less tube 9 arranged in a cavity 8 excited by at least one microwave generator 1 and brought to resonance according to an appropriate mode and is characterised in that it consists in orienting the polarised stationary electric field E, of constant amplitude, parallel to the axis of the discharge tube 9 and in over-dimensioning the cavity so that this tube has its longitudinal dimension along a resonance antinode of the mode excited in the cavity. <IMAGE>
