Abstract
Equations for the modulation products in the multi-signal analysis of an amplitude- and phase-modulated traveling-wave amplifier have been programmed and the results computed. The computation includes all three theoretical approaches derived and discussed in previous reports. These include the nonlinear approach using the two-signal input, the large-signal analysis using the multiple signal input and the Boltzmann transport equation approach using the multiple signal input. The output powers of some important cross-modulation components, the cross-modulation factors, etc. are presented in graphs. Experimental results using two and three signal inputs are presented for comparison. A large-signal analysis is carried out for a d-c pumped quadrupole amplifier employing cyclotronsynchronous wave interaction. Criteria for the validity of small-signal and large-signal analyses are established by means of the phase slip. Energy relations between the beam and the pumping field are discussed for a strong pumping field condition that would lead to the anomalous gain possibility. The technique for insertion of the helix-BeO rod into a metal envelope to improve the thermal conductivity of the assembly is developed. (Author)
