Frequency domain simulation of drive induced oscillation in a coupled-cavity TWT
TL;DR: In this article, a multi-frequency, frequency domain model was proposed to analyze drive induced oscillation (DIO) in wide-band coupled-cavity TWTs, where the stability of the amplifier is tested by introducing a small amplitude test wave with frequency near that of the 2π-mode.
Journal ArticleDOI
Higher harmonic generation in the induced resonance electron cyclotron maser
TL;DR: In this paper, a set of fast-time averaged nonlinear equations of motion is derived for the particle motion near an arbitrary harmonic at any index of refraction, and the small signal efficiency is computed analytically and the minimum current to start the cavity oscillations is obtained.
Journal ArticleDOI
Observation of an Electromagnetically Driven Temperature Wave in Porous Zinc Oxide During Microwave Heating
D. Dadon,D. Gershon,Yuval Carmel,Kirill I. Rybakov,R. Hutcheon,A. Birman,L. P. Martin,Jeffrey P. Calame,Baruch Levush,M. Rosen +9 more
TL;DR: In this paper, a sharp temperature wave was observed during microwave heating of porous zinc oxide in nitrogen and argon atmospheres, which was attributed to an anomalous peak in the imaginary part of the complex permittivity possibly caused by desorption of chemisorbed oxygen from the surfaces of ZnO crystallites.
Proceedings ArticleDOI
Experimental progress on the development of a multiple-beam klystron with 13% bandwidth
David K. Abe,Dean E. Pershing,Edward L. Wright,Khanh T. Nguyen,F.N. Wood,Robert E. Myers,Edward Eisen,Baruch Levush +7 more
TL;DR: In this paper, the development of a multiple-beam klystron (MBK) designed to operate in S-band with a 1-dB bandwidth of 13% was presented, powered by an 18-beam electron gun operating at a voltage of 42 kV and a total current of 41.6 A.

TL;DR: In this article, a significant level of effort by SAIC and BWR, funded by ONR and JTO, has been made to enhance the three dimensional finite element (3D) finite-element (FE) electrostatic timedomain (ESTD) particle-in-cell (PIC) code MICHELLE to provide modeling and simulation of the interaction of electron emission sources in the presence of electromagnetic cavity fields.
