Two fast vertical beam profile monitors have been implemented at the Cornell electron storage ring (CESR); one is dedicated to electrons, the other to positrons. They are being used to probe a range of single bunch and multi-bunch beam dynamics issues as well as machine stability issues. Readout is based on the Hamamatsu H7260K multi-anode photomultiplier [1]. This device has a 32 channel linear anode array with 1 mm channel pitch and sub-nanosecond rise time. A custom 72 MHz digitizer unit allows synchronous multi- bunch and turn-by-turn data acquisition of the 14 ns spaced bunches in CESR. An on-board digital signal processor provides local data processing capability. This paper describes the profile monitor hardware, data acquisition system, and data analysis software.
