Claim 1
Independent Claim
102 words
A METHOD FOR TUNING AN ARCH DISCHARGE COMPRISING THE STEPS OF INITIATING SAID DISCHARGE WITHIN AN EVACUATED ENCLOSURE AND WITHIN A MAGNETIC FIELD BETWEEN A HOLLOW GAS-FED CATHODE AND AN ANNULAR WITH AN AXIALLY DISPOSED REFLECTOR ELECTRODE DISPOSED BETWEEN SAID ANODE AND SAID CATHODE TO FORM SAID DISCHARGE IN THE SHAPE OF A CYLINDRICAL PLASMA, AND ADJUSTING THE DIAMETER OF SAID CYLINDRICAL DISCHARGE BY ADJUSTING THE DIAMETER OF SAID REFLECTOR ELECTRODE, WHEREBY THE DOMINANT FREQUENCY IN THE FREQUENCY SPECTRUM OF SAID DISCHARGE CAN BE ADJUSTED TO PROGRESSIVELY LOWER AND HIGHER VALUES AS A FUNCTION OF THE DIAMETER OF SAID CYLINDRICAL ARC DISCHARGE.
