ELECTROMAGNETIC WAVE-CHARGE INTERACTION IN CROSSED FIELDS.

Abstract

The purpose of the work on this contract is to investigate the interaction of electromagnetic waves and charge carriers in vacuum and solids. A crossed-field microwave vacuum-tube amplifier has been designed for low-noise operation. The paraxial crossed-field gun design method has been extended to use on magnetically shielded guns. A study of optically stimulated emission from a cathode of suitable form for a crossed-field tube has been conducted. An experimental and theoretical study of electromagnetic and space-charge waves in semiconductors has been performed. A study has been made of the propagation and amplification of bulk acoustic waves in crossed electric and magnetic fields. A study of surface-wave amplification on InSb in crossed electric and magnetic fields has been made. (Author)
