100-MHz power amplifier design and control for a heavy-ion accelerator
Description
Design details are given for a typical power amplifier and its control systems to be used for the approximately 80 spiral resonating cavities of the proposed heavy-ion accelerator at Los Alamos Scientific Laboratory. Operational procedures and some experimental results are also described. Plate circuit design is important for maximum efficiency and stability. The original movable-short, fixed-tap design was not optimal, and several improvements are described. Perturbation controllers are required for the cavity rf phase, amplitude, and resonant frequency. The amplitude control is done by varying the power amplifier screen-grid voltage. Typical power amplifier output is 20 kW at 33 percent plate efficiency and 19-dB gain. (U.S.)
