Claim 1
Independent Claim
198 words
AN ELECTRON TUBE APPARATUS COMPRISING AN ELONGATED CATHODE ELECTRODE FOR PRODUCING A SHEET BEAM OF ELECTRONS, MEANS FOR ACCELERATING SAID BEAM ALONG A PREDETERMINED PATH, A SLOW WAVE STRUCTURE FOR PROPAGATING ELECTROMAGNETIC WAVE ENERGY INCLUDING A PLURALITY OF CONDUCTING SECTIONS EXTENDING IN ONE TRANSVERSE DIRECTION WITH RESPECT TO THE BEAM PATH AND IN MUTUALLY SPACED RELATED IN THE OTHER TRANSVERSE DIRECTION WITH RESPECT TO THE BEAM PATH FOR PRODUCING ELECTRIC FIELDS IN SAID PATH IN SAID OTHER TRANSVERSE DIRECTION WITH RESPECT TO THE PATH OF THE SHEET BEAM FOR IMPARTING COMPONENTS OF VELOCITY TO ELECTRONS IN SAID BEAM IN SAID OTHER TRANSVERSE DIRECTION, A DRIFT REGION ALONG SAID PATH AND ON THE SIDE OF SAID CATHODE REMOTE FROM SAID SLOW WAVE STRUCTURE WHEREBY ELECTRONS IN SAID BEAM HAVING TRANSVERSE AND LONGITUDINAL COMPONENTS OF VELOCITY ARE CAUSED TO CONVERGE AS A RESULT OF THE TRANSVERSE COMPONENTS OF VELOCITY INTO BUNCHES AND AN OUTPUT CIRCUIT COMPRISING AN ELONGATED WAVE GUIDE HAVING A GAP EXTENDING LONGITUDINALLY THEREALONG AND BEING IN PROXIMITY TO SAID PATH WHEREBY ELECTRONS PASSING SAID GAP INDUCE POTENTIALS IN SAID WAVE GUIDE OF A MAGNITUDE GREATER THAN THE MAGNITUDE OF AN ELECTRIC WAVE ON SAID GLOW WAVE STRUCTURE.
