Product design of 200 kilowatt tunable X-band klystron

The paper gives a brief description of the electrical parameters of the tube including 200-kw peak power, NS-db gain, tunable over 8500-95 mc, and 0.005 duty. This provides the background for the description of the construction techniques used to build a tube to survive 30 g shock and vibrational requirements up to 55 cycles. Unique use of stainless steel and copper in the construction of the individual body blocks is described. Ceramic to metal seal techniques are given, and the details of 600° to 650°C processing are described.
