The ALS is a third-generation synchrotron light source currently under construction at LBL. The accelerator complex will consist of a 1--2 GeV electron storage ring, a 1.5 GeV booster synchrotron, a 50 MeV linac, and low and high energy beam transfer lines. Beam pickup devices and electronic instrumentation has been specified for the accelerator, and development of the beam position monitor (BPM) systems is well under way. Considerable effort has gone into the storage ring BPM system design in particular because of the need for very fast and accurate measurements. We meet the speed and accuracy requirements in the electronics with parallel processing and error correction techniques. A tuned receiver is provided for every beam position pickup, and for every array of four pickups there is a microprocessor controlling the measurement and recording data. In this paper we report on the requirements, design, and performance of the storage ring BPM system. 3 refs., 3 figs.
