Abstract :
The Alternating Gradient Synchrotron (AGS) booster has two RF systems covering a frequency range from 600 kHz to 4.2 MHz. The low frequency system, also called Band II, operates on a frequency range from 600 kHz to 2.4 MHz. 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. Commissioning of the booster is underway with proton beams.<>
