Abstract
The Proton Storage Ring (PSR) is a facility used for high intensity neutron studies at the Los Alamos Meson Physics Facility(LAWF), located at the Los Alamos National Laboratories, Los Alamos, New Mexico. A wide bandwidth beam position processor is needed to study proton beam instability effects in the PSR that limit its operation. A wide bandwidth beam position monitor (BPM) processor was designed, prototyped, and tested for the Proton Storage Ring. The processor can provide data on head-to-tail beam displacement, and beam oscillations. The bandwidth of the processor is over 50 [ ] allowing detection of beam oscillation frequencies in excess of 15 times the revolution frequency of the beam in the PSR. The processor also has a wide dynamic range to process the widely varying beam intensities in the PSR. New data acquisition hardware was implemented to accurately measure and record the high frequency waveforms necessary to characterize the processor performance. Data acquisition and analysis software was written to facilitate the testing process.
