Abstract:

Backward-wave-amplifier gain near the start of self-oscillation is computed for the large-C case, and a design of equipment for experimental measurements of noise along an electron beam is presented. The problem of relating the circuit and beam equations for the backward-wave oscillator is discussed, and a method of solution is suggested for the linear case. Assembly of a spectrum analyzer to measure self-spectra and cross spectra was begun and was almost completed. To test the noise reduction method suggested by Dr. C. C. Wang, an experimental layout is proposed that will not need good slow-wave couplers. The necessary modifications for further tests of the experimental traveling-wave tube are discussed. Some calculations are performed to show the effect of the QC product on the properties of helical slow wave couplers. Network functions are obtained that yield a noisy communication network for which the total error is minimized. Author
