Abstract :
RF amplifiers for accelerators are expensive. To reduce their cost,Diversified Technologies,Inc. (DTI) is developing a modular amplifier design under a DOE SBIR grant. This amplifier can produce outputs at different frequencies by changing the output tube and drive amplifier,while retaining common components,including the communication, controls, and power supplies. DTI is designing and building the initial version of this amplifier for a proposed energy-recovery linac at Argonne National Laboratory. The amplifier will deliver 20 kW CW at 704 MHz with an amplitude variation less than 0.01%. This paper discusses the specifications and design of the amplifier.
