  • Abstract
    Spurious oscillations in high power klystrons are found to occur in the gun region, in the cavities in the main body of the tube, or in the drift tunnel. The criteria that determine whether a mode will oscillate is that its beam loading be negative, and that the power it extracts from the beam exceeds its losses to external loading and wall dissipation. Using the electromagnetic and particle-in-cell modules of MAFIA, we have devised numerical techniques with which the quality factors Qb, Qe, and Qo can be evaluated and compared. Simulations involving a gun oscillation observed in the SLAC/DESY S-band klystron will be reported
