Patent ID: 7002300

Claim:
A microwave generator ( 11 ) with a radiation antenna ( 26 ) which is connected to capacitors ( 13 ) which are to be recharged, and a high-voltage generator ( 35 ) comprising an energy supplier for charging up the capacitors ( 13 ), wherein the high-voltage generator ( 35 ) is connected through the radiation antenna ( 26 ) to a coaxial succession of annular capacitors ( 13 ) which are sequentially connectable in parallel with each other, said capacitors ( 13 ) possessing first and second electrodes ( 15 , 16 ), each capacitor having a respective tubular said second counterpart electrode ( 16 ) connected together with the other electrode ( 16 ) while the first electrode ( 15 ) is connectable by a switch ( 39 ) to the most closely adjacent further electrodes ( 15 ), and wherein disposed in the interior of a respective tubular said second electrode ( 16 ) are a number of axially mutually spaced annular said first electrodes ( 15 ).
