Abstract

A beam position measurement (BPM) system for VEPP2000 collider has been developed in BINP. 4 electrostatic pickups with diameter of vacuum chamber of 40 mm have been installed in ring. BPM system is able to measure the position of each of 2 bunches at every turn for beam current range 1÷100 mA. The resolution of measurement of the single bunch is about 100 microns for beam current of 10 mA. The features of system design, the main parameters and results obtained in VEPP2000 ring are presented.
