E.A. Bekhtenevª, E.N. Dementev, G.V. Karpov, Yu.A. Rogovsky Budker Institute of Nuclear Physics Siberian Branch of the Russian Academy of Sciences, Novosibirsk, Russia 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. ª – corresponding author |

Shwartz Budker Institute of Nuclear Physics Siberian Branch of the Russian Academy of Sciences, Novosibirsk, Russia Abstract Round colliding beams option in VEPP-2000 [1] puts a number of strict requirements on the collider lattice. The orbit Response Matrix (ORM) technique is a versatile tool for lattice analysis and correction. For linear optical function study and correction, the orbit response to the dipole correctors is collected and processed, while for the orbit correction the quadrupole trimming is used. Theoretical and experimental responses of closed orbit to the same perturbations are compared to determine the most probable deviations of chosen parameters from its design values. ª – corresponding author |
