CESR Beam Instrumentation DAQ User Requirements: Seamless access from multiple applications High priority for orbit and phase taking from BPMs High priority, fast communication for 10W & 10E BPMs, FLM, BSM. BPMs deliver position and tunes. Control of gain and timing for hard-shaking, injection Configurable DSP for special experiments Synchronized information from all sources with ability to decouple for fast, multiple access 2/24/2019 J.
