INVESTIGATION OF LINEAR BEAM AND NEW CONCEPTS OF MICROWAVE POWER GENERATION.
Abstract
The shielded-gun (Brillouin flow) beam tester, when outfitted with a larger pinhole in the probe, yielded satisfactory noise growth data which is highly reminiscent of peak velocity growth data previously reported. Studies have continued of efficiency enhancement of multi-cavity klystrons resulting from the application of d.c. bias to the electron beam. In the studies of the efficiency of two-cavity klystrons, the optimum location of the output cavity was determined theoretically for two cases; the conventional gridless cavity case and a gridless double-gap cavity. The nanosecond pulse studies of linear beam tubes has been extended into the nonlinear operating range. The d.c. beam and plasma diagnostic measurements obtained on the Plasma Analyzer are discussed. Initial results have been obtained on the formation of an electron beam using laser-stimulated emission. A simple theory has been formulated for the beam admittance characterizing the dense electron beam obtained from laser-stimulated emission.
