BASIC RESEARCH IN MICROWAVE DEVICES AND QUANTUM ELECTRONICS.
Abstract
Generation and Amplification of Coherent Electromagnetic Energy in the Millimeter and Submillimeter Wavelength Region; An experimental lowfrequency model of the frequency multiplier has been designed. A scheme of feedback to enhance the transfer efficiency is included. The tube is in the final stage of assembly and alignment. Difficulties in loading a helix designed to operate at 30 Gc into a BeO tube have not been fully resolved. Experimental data indicates that a material having a higher resiliency than tungsten should be used for the helix. Analysis of Amplitude-and Phase-Modulated Traveling-Wave Amplifiers; The analysis of the operation of the TWA with a multi-frequency input has been extended to account for the multivalued nature of the electron velocity in the beam. Boltzmann's transport equation is used to describe the kinematics of the electron beam. Study of a D-c Pumped Quadrupole Amplifier; A comprehensive study of the coupling mechanism between the various modes of operation of a d-c pumped transverse wave device has been made by means of the coupled-mode theory.
