Possibility of MW-Level Second-Harmonic Generation in a Gyrotron Locked by an External Signal
G. G. Denisov,Irina V. Zotova,I. V. Zheleznov,Andrey M. Malkin,E. S. Semenov,A. S. Sergeev,Naum S. Ginzburg,M. Yu. Glyavin +7 more
TL;DR: In this article, the authors theoretically study the possibility of high-power (MW-level) generation in second-harmonic gyrotrons based on the frequency-locking by a weak (several percent of the power) external monochromatic signal.
Proceedings ArticleDOI

Gyrotron cavity with an optimized profile
G. G. Denisov,N. L. Aleksandrov,D. A. Lukovnikov,Mikhail A. Moiseev,N. A. Zavolsky,V. E. Zapevalov +5 more
TL;DR: In this article, a modified gyrotron cavity is proposed, where an optimized profile of the cavity wall allows decreasing the maximal thermal load on the wall while the electron efficiency stays high.
