VARIABLE NO DELAY LINE FOR PROGRESSIVE WAVE TUBE, AND PROGRESSIVE WAVE TUBE PROVIDED WITH SUCH A LINE

摘要

P THE INVENTION CONCERNS A VARIABLE NO DELAY LINE FOR PROGRESSIVE WAVE TUBE. / P P THE LINE IS CONSISTING OF CELLS 10 BUILT IN SECTIONS 11 OF THE WAVEGUIDE IN WHICH THE PROPAGATION IS PLACED OF THE ELECTROMAGNETIC WAVE PLACED IN THE OPERATION OF THE TUBE. ALL CELLS ARE CONSISTING OF THE SAME ELEMENTS, CEILINGS 1, RING 3, ROD BRACKET RODS 4, SHORT-CIRCUIT 2. THE VARIABLE STEP IS OBTAINED BY EXPANSION OR CONTRACTION OF SIDES WITHIN THE GUIDE SECTION. A SENSITIVE IMPROVEMENT IN THE PERFORMANCE OF THE TUBE IS OBTAINED BY THE USE OF LINES MADE OF THREE PARTS OF DIFFERENT PITCHES, SUCCESSFUL ALONG THE BEAM PATH, THE SECOND OF WHICH PRESENTS A LOWER STEP AND THE THIRD ONE STEP GREATER THAN THE ONE OF THE PREMIERE / P P APPLICATION TO THE PRODUCTION OF HIGH LEVELS OF POWER WITH HIGH BANDWIDTH IN CENTIMETRIC WAVES. / P
