Design of the AGS Booster beam position monitor electronics

The operational requirements of the AGS (Alternating Gradient Synchrotron) Booster beam position monitor system necessitate the use of electronics with wide dynamic range and broad instantaneous bandwidth. Bunch synchronization is provided by a remote timing sequencer coupled to the local ring electronics via digital fiber-optic links. The sequencer and local ring circuitry work together to provide single turn trajectory or average orbit and intensity information, integrated over 1 to 255 bunches. Test capabilities are included for the purpose of enhancing BPM system accuracy. The authors describe the design of the Booster beam position monitor electronics and present performance details of the front-end processing, acquisition, and timing circuitry.<
