Abstract :
A computer-aided study has been conducted to determine the performance capability of Ka-band klystrons. Basic design parameters are explored, with particular attention given to beam formation and confinement, thermal considerations, and RF circuit parameters. Two illustrative conceptual designs are presented. One offers 250-kW peak power and 50% efficiency, and the other offers 3-kW peak output power and 340-MHz bandwidth. The possibility of extending average power output to over 2 kW is discussed.<>
