Developed in BINP wideband beam position monitor (BPM) electronics has been installed at the VEPP-4M electron-positron collider. The VEPP-4M operates with two electron and two positron bunches. Wide bandwidth of new electronics (200 MHz) allows the separate measurements of electron and positron bunches with time interval between bunches up to 18 ns. 18 BPMs located near four meeting points are supplied with new electronics. The electronics can measure the position of each of four bunches. BPM system works at two modes: slow closed orbit measurements and turn-by-turn measurements. We present details of system design and operation.

  Pick-ups are one of the most widespread non-destructive diagnostics at charged particle accelerators. These detectors, also known as beam position monitors, are generally used for the center-of-mass position measurements of bunched beams. The paper describes the research results for infrequent case of debunched beams operation. Measurement peculiarities and distinctive features of electronics are presented. The results of test bench-based measurements and 3D finite element simulations are discussed.
