APPLICATIONS OF BEAM DIAGNOSTIC SYSTEM AT THE VEPP-4.

Advanced applications of the beam diagnostic systems installed at the 6GeV electron-positron collider VEPP-4M and its 2GeV booster VEPP-3 [1], are described. The systems are based on a turn-by-turn processing of signal measured by electrostatic beam position monitors [2]. A technique for beta function correction has been used for adjustment of the VEPP-4M magnet structure. This technique is based on measurement of amplitude of free coherent betatron oscillations, proportional to the square root of beta function. Results of the measurements are given. A new method for observation of non-linear betatron motion on phase space, using a single beam positio
