Neutrode crossed field voltage tuned oscillator

Claim 1

A MAGNETRON APPARATUS COMPRISING AN ANODE HAVING A PLURALITY OF CAVITIES SEPARATED BY CONDUCTIVE SEGMENTS THEREBETWEEN ALONG A PREDETERMINED PORTION THEREOF PROVIDING A SLOW WAVE STRUCTURE, IMPEDANCE MEANS TERMINATING SAID SLOW WAVE STRUCTURE, AN ELECTRODE ALONG ANOTHER PORTION OF SAID ANODE, A CATHODE, SAID SEGMENTS AND SAID ELECTRODE EACH HAVING EXTREMITIES SPACED FROM SAID CATHODE AND DEFINING THEREWITH A REENTRANT ELECTRON PATH, SAID ELECTRODE BEING INSULATED FROM SAID ANODE AND SAID CATHODE, MEANS IMPRESSING AN ELECTRICAL POTENTIAL ON SAID ELECTRODE DIFFERENT FROM THAT APPLIED TO SAID ANODE TO ESTABLISH AN ELECTRIC FIELD BETWEEN SAID CATHODE AND SAID ELECTRODE DIFFERENT FROM THE ELECTRIC FIELD IN THE REGION BETWEEN SAID ANODE AND CATHODE, MEANS PRODUCING A MAGNETIC FIELD BETWEEN SAID CATHODE AND BOTH SAID ANODE AND SAID ELECTRODE HAVING LINES OF FORCE SUBSTANTIALLY PERPENDICULAR TO THE LINES OF SAID ELECTRIC FIELDS TO PRODUCE A DIFFERENT AVERAGE VELOCITY OF ELECTRONS IN THE PORTION OF SAID ANODE IN THE REGION OF SAID ELECTRODE AND DETERMINE THE SPACING BETWEEN ELECTRON BUNCHES IN THE PORTION OF THE ELECTRON PATH BETWEEN SAID CATHODE AND SLOW WAVE STRUCTURE BY THE POTENTIALS APPLIED TO SAID ELECTRODES.
