DEVELOPMENT OF THE SIRIUS RF BPM ELECTRONICS

A Beam Position Monitor (BPM) system is being developed for the new low emmitance 3 GeV Brazilian synchrotron light source, Sirius. The Sirius BPM electronics is a modular system based on a PICMG MicroTCA.4 platform using ADC mezzanine cards in ANSI/VITA 57.1 FMC form factor and standalone RF front-end boards. It has been designed under the CERN Open Hardware License (OHL) by the Brazilian Synchrotron Light Laboratory (LNLS) in collaboration with the Warsaw University of Technology (WUT). This paper presents the overall architecture of the Sirius BPM electronics system and performance evaluation of its first prototype, comprehending beam current, filling pattern and temperature dependences, and position measurement resolution as a function of the beam current.
