Traveling wave device

Claim 1

AN ELECTRON DISCHARGE DEVICE COMPRISING: AN ANODE STRUCTURE; SAID ANODE STRUCTURE HAVING A PLURALITY OF PARALLEL AXIALLY-EXTENDING VANES DEFINING A PLURALITY OF LINEAR UNCOUPLED ELECTROMAGNETIC WAVE CONDUCTING PATHS EXTENDING FROM OPPOSITE SIDES OF A COMMON SUPPORT MEMBER; MEANS AT THE ENDS OF SAID PATHS FOR CAUSING THE PHASE OF WAVES IN SPACES BETWEEN SAID VANES TO CHANGE IN VALUE FROM SPACE TO SPACE; AN ELECTRON EMITTING CATHODE STRUCTURE COEXTENSIVE WITH SAID ANODE STRUCTURE DEFINING A SUBSTANTIALLY CONTINUOUS INTERACTION SPACE THEREBETWEEN; SAID INTERACTION SPACE VIEWED IN CROSS-SECTION HAVING TWO PARALLEL STRAIGHT SECTIONS JOINED BY CURVED SECTIONS WITH SAID ANODE VANES BEING PROVIDED AT SAID STRAIGHT SECTIONS; MEANS FOR ESTABLISHING A MAGNETIC FIELD DIRECTED PARALLEL TO THE AXIS OF SAID ANODE STRUCTURE AND AN ELECTRIC FIELD DIRECTED RADIALLY TO SAID AXIS WHEREBY THE ELECTRONS FORM A SPACE CHARGE IN THE INTERACTION SPACE WHICH CIRCULATES SUBSTANTIALLY CIRCUMFERENTIALLY; MEANS FOR DIRECTING ELECTROMAGNETIC WAVES ALONG THE WAVE CONDUCTING PATHS IN AN AXIAL DIRECTION TO RESULT IN FRINGING ELECTRIC FIELDS BETWEEN ADJACENT VANES EXTENDING INTO THE INTERACTION SPACE; SAID CROSSED MAGNETIC AND ELECTRIC FIELDS TOGETHER WITH SAID FRINGING ELECTRIC FIELDS IMPARTING A PHASE FOCUSING EFFECT TO THE ELECTRON SPACE CHARGE SUCH THAT THE CROSSOVER POINT OF SAID SPACE CHARGE AND TRAVERSED WAVES IS IN VELOCITY SYNCHRONOUS RELATIONSHIP ALONG A PATH COAXIAL TO SAID LINEAR WAVE PATHS WHEREBY SAID WAVES ARE AMPLIFIED BY THE NET FLOW OF ENERGY FROM THE ELECTRON SPACE CHARGE; AND A MEANS FOR LAUNCHING SAID AMPLIFIED WAVES FROM THE ENDS OF EACH OF SAID PATHS.
