The problem of feeding a pulsed megnetron into a high Q (greater than 10,000) circuit was solved by incorporating a high power ferrite isolator into the appropriate microwave circuit. The PACE analogde computer has been programmed, and curves of particles displacement and velocity have been computed for field strengths from 50 to 500 kv/ cm and injection velocities ranging from 0.24 to 0.40c. Analysis of the slow-wave, dielectric, higher order mode resonator included the computation of the TE mode design curves, plots of the mode patterns, and the preparation of a five mm experiment using the rebatron. Detailed theoretical investigations of the general behavior of the Harmodotron were made. The TM and TE modes of metal and dielectric cavities were compared. Analog circuits were examined to determine the limiting efficiency for frequency conversions in crystal multipliers. A mount in which the Wollaston wire was etched directly in the mount, was designed for the bolometer detector. (For preceding period see AECU-3594.) (J.S.R.)
