Abstract :
We describe the design and initial characterization of a fast (nanosecond time scale), high resolution (micron level) beam position monitoring system for use in the Cornell Electron Storage Ring (CESR). Beam position monitoring requirements at CESR include 1) precision orbit measurements in the interaction region and near the synchrotron x-ray beam lines, 2) monitoring of individual bunch positions during multi-bunch high energy physics (HEP) operation, 3) single pass measurements to monitor injected bunch oscillations and injection transients, and 4) operation at both HEP and injection current levels which vary by 5 orders of magnitude. The ready availability of electronic components with large bandwidth and dynamic range for the communications industry has allowed us to economically implement a system providing this range of capabilities
