Abstract:
1. A microwave generator, comprising: a resonator having two mutually spaced resonator electrodes forming a spark gap device configured to break down upon being subjected to a firing voltage applied therebetween; said spark gap device being formed with at least two spark gaps connected in parallel with one another, said resonator electrodes being disposed with a defined spacing, and the spacing of said resonator electrodes being reduced at said spark gaps to a substantially identical smaller spacing; said resonator electrodes being disposed to form a coaxial resonator structure with an inner electrode substantially in the form of a cylindrical casing and an outer electrode surrounding said inner electrode, at least one of said inner electrode and said outer electrode being formed with projections projecting in a direction towards the respectively opposite said electrode, defining spacing distances between said electrodes in the region of said projections less than each spacing distance between said electrodes outside the region of said projections, and said spacing distances between said electrodes in the region of said projections being substantially identical to one another, said inner electrode being closed at one end by a closed end disposed opposite from an end face that closes off said outer electrode, said projections being formed in a region of said closed end of said inner electrode and/or in a region of said end face of said outer electrode.
