Abstract
Generation and Amplification of Coherent Electromagnetic Energy in the Millimeter and submillimeter Wavelength Region: The construction of the experimental low-frequency model of the frequency multiplier with feedback scheme to enhance the transfer efficiency has been completed. D-c beam testing shows that the tube is aligned satisfactorily. The tube is now awaiting final r-f testing. Difficulties of brazing a 30 Gc helix into a BeO tube have not been resolved. Techniques involving the use of Fansteel 60 metal are being developed. Analysis of Amplitude and Phase-Modulated Traveling-Wave Amplifiers: A nonlinear theory of the amplitude and phasemodulated traveling-wave amplifier with a multiple frequency input is developed. Computer results for some typical cases are presented and interpreted. Study of a D-c Pumped Quadrupole Amplifier: The mechanism of an anomalous gain predicated for the cyclotron-to-synchronous wave interaction is explained in terms of kinetic power relations. Experimental results from other sources give support to this theory. (Author)
