Claim 1
Independent Claim
180 words
AN ELECTRON BEAM AMPLIFYING TUBE COMPRISING: AN ELECTRON GUN FOR PROVIDING A RELATIVELY LOW VELOCITY BEAM OF ELECTRONS DIRECTED ALONG THE LONGITUDINAL AXIS OF THE TUBE; AN ANODE RECEPTIVE OF SAID BEAM; CONTAINMENT MEANS INCLUDING A PLURALITY OF ELECTRODE ASSEMBLIES CENTERED AROUND THE AXIS FOR PROVIDING TWO-DIMENSIONAL TRANSVERSE CONTAINMENT OF SAID BEAM BETWEEN SAID GUN AND SAID ANODE, WITH EACH OF SAID ASSEMBLIES COMPRISING A PLURALITY OF LONGITUDINALLY ALIGNED AND ELECTRICALLY DISTINCT CONDUCTIVE ELEMENTS; ELECTROSTATIC FOCUSING CIRCUIT MEANS FOR ENERGIZING SAID CONTAINMENT MEANS WITH A UNIDIRECTIONAL VOLTAGE DEPENDENT UPON THE TRANSVERSE SPACING OF SAID CONTAINMENT MEANS SO THAT SAID BEAM IS BOUND TO THE AXIS BY ALTERNATE GRADIENT FOCUSING; ELECTRIC CIRCUIT MEANS FOR IMPRESSING INPUT SIGNALS ON A FIRST SECTION OF THE LENGTH OF SAID CONTAINMENT MEANS TO IMPART TRANSVERSE OSCILLATIONS TO SAID ELECTRONS; ELECTROSTATIC AMPLIFYING CIRCUIT MEANS FOR IMPRESSING AN AMPLIFYING UNIDIRECTIONAL VOLTAGE IN ANOTHER SECTION OF THE LENGTH OF SAID CONTAINMENT MEANS TO INCREASE ANY LATERAL DEFLECTION OF SAID BEAM AS A FUNCTION OF SAID TRANSVERSE OSCILLATIONS; AND MEANS FOR DETECTING THE CHARACTER OF SAID INCREASED LATERAL DEFLECTION.
