ON MULTIPLIER KLYSTRONS WITH TRAVELLING WAVES (OB UMNOZHITELNYKH IKLISTRONAKH S BEGUSHCHEI VOLNOI),
Abstract
The operating principle of the described klystrons is based on the interactions between an electron beam and traveling electromagnetic waves in wave guides. This interaction makes possible velocity modulation of the electron beam and the extraction of high-frequency power from the system. The simplest wave guide multiplier klystron and its operation are illustrated. Such a klystron has the advantage over ordinary klystrons in that its bandwidth is considerably greater. The frequency can be tuned either by varying the phase velocity of the exciting current wave or by varying the phase velocity of a given mode of the electric field. Equations are derived for the output power and the efficiency of such a klystron and it is shown that by using periodic loading it is possible to raise the efficiency from 35 to 50%. A modification of the double-wave guide klystron, namely a klystron with annular wave guides is also discussed. Such a klystron has the same efficiency as an ordinary klystron, but since the frequency and oscillation mode are independent of the diameter of the annular wave guides employed, the klystron can be made up of large wave guides and accommodate more powerful electron beams.
