The Signal Processing Electronics for the Beam Position Monitors of Russian Fourth Generation Synchrotron Radiation Source

— The project of fourth-generation Ultimate Source for Synchrotron Radiation (USSR-4) is under development in Russia by leading of National Research Center “Kurchatov institute”. Some of diagnostic systems required for the new facility have to be developed or redeveloped to satisfy the features of the new facility. Hundreds beam position monitors (BPM) are installed along beam transfer lines, booster and storage rings to control the electron beam position. In booster and storage ring the electronics of BPM has to provide both the normally beam circulation and the first beam turn operation. It has to provide beam position monitoring in the bunch-by-bunch option for all operational modes [1]. In this manuscript we discuss the architecture of the BPM electronics, important aspects of the analog front-end, available components and a resulting performance of designed electronic module.
