Beam-plasma microwave noise generators

Claim 1

A DISCHARGE DEVICE FOR GENERATING STRONG NOISE SIGNALS HAVING AN UPPER NOISE FREQUENCY FS COMPRISING A DISCHARGE CHAMBER, AN IONIZABLE GAS IN SAID DISCHARGE CHAMBER, SAID GAS HAVING AN INTERNAL GAS PRESSURE OF AT LEAST 10-4 MM. HG AND AT MOST 10-2 MM. HG, ONE ANODE ELECTRODE AND AT LEAST ONE CATHODE ELECTRODE IN SAID DISCHARGE CHAMBER, SAID ANODE ELECTRODE BEING DISPLACED FROM SAID CATHODE ELECTRODE, MEANS CONNECTED TO SAID ANODE ELECTRODE AND SAID CATHODE ELECTRODE FOR ESTABLISHING AN ELECTRIC FIELD IN THE DISCHARGE VOLUME BETWEEN SAID ANODE ELECTRODE AND SAID CATHODE ELECTRODE WHEREBY A PLASMA OF GAS MOLECULES, IONS AND ELECTRONS IS CREATED IN SAID DISCHARGE VOLUME, SAID PLASMA HAVING A PLASMA FREQUENCY FP, MEANS FOR GENERATING A STATIC MAGNETIC FIELD IN SAID DISCHARGE CHAMBER, SAID MAGNETIC FIELD HAVING A COMPONENT SUBSTANTIALLY PARALLEL TO THE DIRECTION FROM ONE OF SAID ELECTRODES TO THE OTHER OF SAID ELECTRODES WHEREBY ELECTRONS IN SAID PLASMA MOVE IN SPIRAL PATHS ALONG THE FIELD LINES OF SAID MAGNETIC FIELD WITH A CYCLOTRON FREQUENCY FC AND COLLIDE WITH GAS MOLECULES, AND AN OUTPUT CIRCUIT OPERATIVELY ADJACENT TO THE REGION OF THE PLASMA FOR RADIATIVELY RECEIVING THE DYNAMIC ELECTROMAGNETIC FIELDS OF NOISE ENERGY GENERATED IN SAID PLASMA, THE STRENGTH OF SAID MAGNETIC FIELD AND THE DENSITY OF SAID PLASMA BEING SUCH THAT FC>FS AND FP>FS.
