Abstract :
A high-level RF system, including a power amplifier and cavity, has been designed and built for the Alternating Gradient Synchrotron (AGS) Booster. It covers a frequency range of 2.4 to 4.2 MHz and will be used to accelerate high-intensity protons, low-intensity polarized protons and heavy ions to the 1.5-GeV level. A total accelerating voltage of up to 90 kV will be provided by two cavities, each having two gaps. The internally cross-coupled, pushpull cavities are driven by an adjacent power amplifier. In order to accommodate beam intensities of up to 0.75*10/sup 13/ protons per bunch, a low plate resistance power tetrode is used. The tube anode is magnetically coupled to one of the cavity´s two parallel cells. The amplifier is a grounded cathode configuration driven by a remotely located solid-state amplifier. It has been tested in the laboratory at full gap voltage with satisfactory results.<>
