The AGS Booster low frequency rf system

Conference ·
OSTI ID:5773313
An rf system has been designed to accelerate all the desired species of ions up to Gold, which will be available at {beta} = 0.048. The system will run on different harmonic numbers (h). It will start from h = 12 at injection and jump to h = 3 during the cycle. The beam will then be transferred to the high frequency RF system that will bring it to the extraction energy. The low frequency system consists of two single gap cavities that sweep from 0.6 to 2.4 MHz, with gap voltages up to 17 kV. The cavities are loaded with TDK SY7 high permeability ferrite rings. Tuning will be accomplished by changing the permeability of the ferrite with dc bias currents as high as 200 A flowing in two figure of eight'' windings. The cavity will be driven by a 200 kW push-pull tetrode power amplifier, which will be driven by remotely located solid state drivers. 5 refs., 2 figs., 2 tabs.
