Abstract
A new frequency multiplier tube that will have a better overall conversion efficiency has been designed. The enhancement in efficiency is derived from the fact that a section of d-c pumped quadrupole amplifier is added to boost the feedback signal to a workable level before introducing it onto the input coupler. Theoretical calculation indicates that enhancement in efficiency up to 100% can be realized. The technique for loading a helix into a B sub E tube is being developed and the best test has proved it to be moderately successful. Equations for the modulation products of two-signal analysis of the amplitude- and phase-modulated traveling-wave amplifier have been programmed and computed. A large-signal analysis of the d-c pumped quadrupole amplifier has been initiated. Equations of motion and the energy relations are derived assuming a specific pump field and neglecting the space-charge forces. From the trajectory of the beam and the energy relation between the beam and the quadrupole, a more exact criterion for the existence of the anomalous gain discussed in previous reports can be established.
