Abstract :
The SOCE is designed with 11 radio frequency cavities (injector - 3, buncher - 2, SOC - 6), each requiring up to 15 kW of rf drive power under full beam loading. A separate three-stage power amplifier unit using an Eimac 4CW25, 000A tetrode as the final amplifier is provided for each cavity. Each unit is provided with automatic servo tuning, and with precise phase and amplitude regulation. A master signal generator supplies a common 50-MHz drive signal, which also serves as the phase reference. Although requirements vary from one cavity to another, all power amplifier units are identical and connected to a single set of dc power supplies and controls. The components were designed conservatively so that the rf system could be operated at greatly increased power levels for high intensity beam studies, with only the addition of an auxiliary dc plate power supply. Most of the design features in the SOCE´s multiple-amplifier radio frequency system will be directly applicable to later SOC-type accelerators, even for a much higher total rf power requirement.
