摘要：

The transport of planar electron beams is a topic of increasing interest for applications to high-power, high-frequency microwave devices. This paper describes two- and three-dimensional simulations of electron-beam transport in a notched wiggler magnet array. The calculations include self-consistent effects of beam-generated fields. The simple notched wiggler configuration can provide vertical and horizontal confinement of high-perveance sheet electron beams with small transverse dimensions. The feasibility calculations address a beam system to drive a 95-GHz traveling-wave tube experiment under construction at Los Alamos National Laboratory, Los Alamos, NM.
