Means using electron bunching apparatus for generating ultra short-wave energy through use of cerenkov effect

Claim 1

A GENERATOR OF ELECTROMAGNETIC WAVES COMPRISING, MEANS FOR PRODUCING A BEAM OF ELECTRONS, MEANS VELOCITY-MODULATING SAID BEAM TO PRODUCE A BUNCHED BEAM OF ELECTRONS, A DIELETRIC MATERIAL HAVING AN APERTURED PORTION THERETHROUGH THROUGH WHICH SAID BUNCHED BEAM PASSES, MEANS ACCELERATING SAID BUNCHED BEAM TO A LINEAR VELOCITY SUCH THAT SAID LINERA VELOCITY OF SAID BUNCHED BEAM PASSING THROUGH SAID APERTURED PORTION IS GREATER THAN THE PHASE VELOCITY OF ELECTROMAGNETIC WAVES IN SAID MATERIAL, SAID ACCELERATING MEANS COMPRISING AN ELECTRODE EFFECTIVELY ENCOMPASSING SAID MATERIAL, A HIGH VOLTAGE SOURCE CONNECTED TO SAID ELECTRODE, SAID VELOCITY-MODULATING MEANS COMPRISING A DIELECTRIC TUBE RESONATOR INTERACTING WITH SAID BEAM, MEANS SUPPLYING ENERGY TO SAID RESONNATOR TO ENERGY-MODULATE SAID BEAM OF ELECTRONS, AND A DECELERATING ELECTRODE INTERPOSED BETWEEN SAID TUBE RESONNATOR AND SAID DIELECTRIC MATERIAL.
