Abstract
THIS PROJECT INVOLVES THE ANALYSIS OF A HIGH HARMONIC, HIGH EFFICIENCY MICROWAVE GENERATOR THAT APPEARS TO BE SUITABLE FOR APPLICATIONS SUCH AS A DRIVER FOR THE NEXT GENERATION OF LINEAR COLLIDERS. THE CONCEPT EMPLOYS A ROTATING "SPIRALING" BEAM TO EXCITE AND AMPLIFY CIRCULARLY POLARIZED MICROWARE RADIATION IN AN INTERACTION OUTPUT WAVEGUIDE. MODULATION OF A LINEAR, HIGH POWER, SMALL DIAMETER BEAM IS OBTAINED IN A DEFLECTION SYSTEM COMPOSED OF A SET OF ROTATING MODE RESONATORS WORKING AT THE DRIVE FREQUENCY. AN OUTPUT WAVEGUIDE IS EMPLOYED TO EFFICIENTLY EXTRACT ENERGY FROM THE ROTATING BEAM AT A FREQUENCY THAT IS A MULTIPLE INTEGER OF THE DRIVE FREQUENCY. INITIAL NUMERICAL ANALYSIS AND SELF-CONSISTENT COMPUTER CALCULATIONS PERFORMED ON A 500 KV, 150 A BEAM, WITH A 2 GHZ DRIVE FREQUENCY, GIVE INDICATION OF HIGHLY EFFICIENT CAPABILITIES (ETA 80%) FOR THE GENERATION OF 50-70 MEGAWATT 10 GHZ MICROWAVE OUTPUT RADIATION. IN PHASE I, DETAILED ANALYSIS AND MULTI-PARTICLE SIMULATION OF THIS CONCEPT WILL BE CONDUCTED IN ORDER TO CHARACTERIZE THE POWER, EFFICIENCY, GAIN, AND OTHER KEY PARAMETERS.
