Abstract :
A beam position monitor system has been developed and used in the commissioning of Brookhaven´s Linac-to-Booster transfer line. This line transports a chopped, RF modulated H/sup -/ beam from the 200-MeV Linac to the AGS Booster. Over a 15-dB dynamic range in beam current, the position monitor system provides a real-time, normalized position signal with an analog bandwidth of about 20 MHz. Seven directional coupler style pickups are installed in the line with each pickup sensing both horizontal and vertical position. A system overview is presented along with results from the commissioning experience.<>
