Discrete cavity model of a standing-wave free-electron laser

Description: A standing-wave free-electron laser (SWFEL) has been proposed for use in a two-beam accelerator (TBA). Unlike a conventional microwave free-electron laser, the SWFEL has a wiggler that is divided by irises into a series of standing-wave cavities, and the beam is reaccelerated by induction cells between cavities. We introduce a one-dimensional discrete-cavity model of the SWFEL. In contrast to the continuum model that has been extensively used to study the device, the new model takes into accoun… more

Modeling of a 1700-MHz cluster cavity of planar triodes

Description: In this paper we present the modeling and design of a 1700-MHz cluster-cavity vacuum tube amplifier. We used a three-dimensional, finite-difference code (MAFIA) to characterize the modes that the resonant structure of the amplifier will support. We describe the characteristics of the tube, including performance predictions. 1 ref., 5 figs., 1 tab.

Photon storage cavities

Description: A general analysis is presented of a photon storage cavity, coupled to free-electron laser (FEL) cavity. It is shown that if the coupling between the FEL cavity and the storage cavity is unidirectional (for example, a ring resonator storage cavity) then storage is possible, but that if the coupling is bi-directional then storage is not possible. Parameters are presented for an infra-red FEL storage cavity giving an order of magnitude increase in the instantaneous photon power within the storage… more
