Abstract :
The aim of our work is the design of a simple and light, small and cheap mm-wave source with moderate power. Our choice has been a 25 kV PPM-focused sheet beam klystron (SBK). However, the efficiency predicted for such a device is very poor: A low beam voltage means small coupling coefficients and a sheet beam profile means a gun with one-dimensional compression only resulting in a low current density. Thus, the performance can be improved by either splitting the wide beam into several round beams with higher current density, or by raising the beam voltage. In this paper the performance of a 25, 50 and 100 kV mm-wave SBK is investigated. Simulation results for the electron guns and the cavity resonators are presented and an overview on the predicted electrical parameters is given
