L-Band High Power Amplifiers for CEBAF Linac

PDF Version Also Available for Download.

Description

The high power portion of the CEBAF RF system utilizes 340 5kW klystrons providing 339 separately controlled outputs. Modulating anodes have been included in the klystron design to provide for economically efficient operation. The design includes shunt regulator-type modulating anode power supplies running from the cathode power supply, and switching filament power supplies. Remotely programmable filament voltage allows maximum cathode life to be realized. Klystron operating setpoint and fast klystron protection logic are provided by individual external CEBAF RF control modules. A single cathode power supply powers a block of eight klystrons. The design includes circulators and custom extrusion and ... continued below

The design includes circulators and custom extrusion and hybrid waveguide components which have allowed reduced physical size and lower cost in the design of the WR-650 waveguide transmission system.
