BPM System for VEPP-4M Collider
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. At present upgrade all 54 BPMs 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.
