Abstract:
1. A microwave generator ( 11 ) with a short-circuit spark gap ( 13 ) between collinearly arranged spark gap electrodes ( 14 – 15 ), wherein the spark gap ( 13 ) is in the form of an untriggered short-circuit switch with a second electrode ( 15 ) arranged opposite an electrode ( 14 ) which is in the form of a spherical cap and by which a charge storage means ( 43 ) having a pot-shaped outer electrode ( 45 ) is dischargeable, through the end portion ( 41 ) of which electrode ( 45 ) there projects the second electrode ( 15 ), and in concentric relationship therewith an inner electrode ( 48 ) which is bulbous in a bottle shape and the end portion of which is the spherical cap-shaped electrode ( 14 ) and is connected collinearly through a bottle neck-shaped reduced portion ( 17 ) thereof to a frustoconical radiating device ( 18 ) disposed substantially outside of the outer electrode ( 45 ), said second electrode ( 15 ) being a pointed electrode, and a plurality of such microwave generators ( 11 ) being arranged in a group ( 10 ) and which are electrically connected in parallel with each other with their charge storage means ( 43 ).
