DEVELOPMENT OF COMPACT ELECTRONICS DEDICATED TO BEAM POSITION MONITORS IN INJECTORS AND BOOSTERS MOTIVATION FOR DEVELOPMENT

Abstract The need for state-of-the-art electronics for dataacquisition and the processing of BPM signals in Injector and/or Booster Synchrotrons is being addressed in a development that aims to make such systems available with less complexity while fulfilling precisely the needs of such specific BPMs. The ESRF Booster Synchrotron uses 75 BPMs in its 300 m circumference to measure the orbit along its acceleration cycle of 50 milliseconds for the electron beam from 0.2 to 6 GeV. The 25-year-old electronics of these BPMs are in need of replacement. While BPM electronics developments in recent years have focused on devices for Storage Rings that face extreme requirements such as sub-micron drift with time, beam intensity, etc. that result in complicated implementation schemes, this new development combines both simplification in the measurement concept and the implementation of new features such as compact design that integrates RF electronics with power-over-Ethernet supply and passive cooling, a powerful System-on-Chip engine and easy communication via SCPI commands. This paper will present the full design concept and its intended functionalities as a BPM device that should offer an excellent price/performance ratio
