Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
135 words
IN A DEVICE USING MULTIPACTOR DISCHARGE, WAVE GUIDE MEANS, A PAIR OF COAXIAL ELECTRODES MOUNTED IN THE WAVE GUIDE MEANS AND FORMING AN ANNULAR MULTIPACATOR SPACE THEREBETWEEN IN ELECTRICAL COMMUNICATION WITH THE WAVE GUIDE MEANS, EACH OF THE ELECTRODES BEING FORMED OF A MATERIAL HAVING A SECONDARY EMISSION COEFFICIENT GREATER THAN UNITY, MEANS APPLYING A RADIAL RF ALTERNATING ELECTRIC FIELD IN THE MULTIPACTOR SPACE TO CAUSE ELECTRONS TO PASS ALTERNATELY FROM ONE ELECTRODE AND TO STRIKE THE OTHER ELECTRODE TO CAUSE A MULTIPACTOR DISCHARGE IN THE CAVITY, MEANS APPLYING AN AXIAL MAGNETIC FIELD WITHIN THE MULTIPACTOR SPACE, SAID ELECTRIC AND MAGNETIC FIELDS CAUSING THE ELECTRONS PASSING BETWEEN SAID ELECTRODES TO FOLLOW CURVED TRAJECTORIES AND TO STRIKE THE ELECTRODES AT ANGLES SUBSTANTIALLY LESS THAN 90* TO THEREBY GREATLY INCREASE THE SECONDARY EMMISSION YIELD FROM THE ELECTRODES.
