Abstract :
A VME based single turn beam position monitor has been developed to improve diagnostics for the NSLS UV ring. A monopulse network processes the PUE pulses, generating the sum and difference signals. An analog processing board amplifies, rectifies, and holds the signals. A digital board then digitizes and stores the data. The system can measure 32,000 turns of bipolar PUE signals from button type electrodes (1 nS per lobe) at a 170 nS repetition rate, with bunches separated by 18.9 nS. The system makes useful measurements over a 40 dB dynamic range of beam current. At full current the resolution is 50 microns
