Computer optimized design of electron guns

IEEE TRANSACTIONS ON PLASMA SCIENCE, 36(1), 156–168.

By: J. David n, R. Ives *, H. Tran n , T. Bui * & M. Read *

author keywords: beam optics analysis; computer optimization; electron gun; implicit filtering; klystron; Nelder-Mead; optimization; simulation; traveling wave tube
TL;DR: This paper considers the problem of designing electron guns using computer optimization techniques, and several different design parameters are manipulated while considering multiple design criteria, including beam and gun properties. (via Semantic Scholar)

2007 journal article

Enhanced features for design of traveling wave tubes using CHRISTINE-1D

IEEE TRANSACTIONS ON PLASMA SCIENCE, 35(4), 1056–1064.

By: J. David n, C. Kory*, H. Tran n , R. Ives * & D. Chernin *

author keywords: DIviding RECTangles (DIRECT); folded waveguide slow-wave circuit; goal functions; Nelder-Mead; optimization; traveling wave tubes (TWTs)
TL;DR: The objectives of this paper are to investigate optimization techniques that may be better suited for this problem (for example, simplex type methods such as Nelder-Mead and Dividing Rectangles); to allow optimization of nonhelix TWTs; and to implement new optimization goal functions.
