manufacturing facilities. This decision was certainly related to the fact that the 1950 Stanford. Mark III electron accelerator employed the first megawatt-level klystrons in the world. Both that accelerator and its 21 klystron amplifiers were built at the University's Microwave Laboratory. The SLAC Klystron Department, dedicated
In a linear-beam tube, as the name implies, the electron beam and the circuit elements with which it interacts are Figure 6.6 Family tree of the distributed emission crossed-field amplifier (CFA). © 1999 CRC Press LLC .. Similar in design to the two-cavity oscillator, the two-cavity klystron amplifier pro- vides limited power
Consider a klystron consisting of two cavities, a. “buncher" and a “catcher," both gridded. (Fig.1). Let a beam of electrons, which has been accelerated by a potential Vo to a velocity uo, traverse the first pair of grids, where it is acted upon by an rf voltage V1sin?t, reduced by a “coupling coefficient" M. The latter modifies the

tection for the body current and the collector current. In most systems, the collector and the body operate at nearly the same potential. Any potential difference is usually only the difference in voltage drop across the various metering circuits. MULTICAVITY POWER KLYSTRON AM- PLIFIERS.— The simple, two-cavity power

As the name implies, this klystron uses two cavities. The first cavity together with the first coupling device is called a “buncher", while the
21 Jan 2004 The velocity modulation (or “bunching") 2-cavity theory that follows immediately is the only large signal analytical treatment of klystrons in this chapter. It leads to the Bessel function coefficients of the current harmonics and a calculation of two- cavity amplifier efficiency. The subsequent derivation of the
A klystron uses one or more special cavities, which modulate the electric field around the axis the tube. Figure 1: mode of operation of a klystron. Due to the number of the resonant cavities klystrons are divided up into: • Multicavity Power Klystrons. • Repeller Klystron. • Two-Cavity Klystron. A klystron uses special cavities
