VEPP 4 - VEPP 2000
Complex of electron-positron collider VEPP-4 - VEPP-2000

OPERATIONAL

 

The VEPP 4 - VEPP 2000 complex is the only Russian complex of installations with colliding beams. The complex includes electron-positron colliders: VEPP-4M with the particle detector KEDR and VEPP-2000 with the detectors CMD and SND, as well as the multi-function electron/positron storage ring VEPP-3. In the detector KEDR, the idea of essentially homogeneous electromagnetic calorimeter on the basis of liquefied krypton was realized for the first time in the world. The physical and technical parameters of the complex enable set-up of world-unique experiments. The results and methods developed are widely used at scientific research organizations, both Russian and foreign. The masses of elementary particles measured with record accuracy are used for description of the fundamental properties of the matter and thus are important information for the world scientific community. In addition to High Energy Physics research, the complex is involved in experiments using synchrotron radiation extracted from the installations VEPP-3 and VEPP-4M. Beams of synchrotron radiation are used in experiments on properties of materials, nanostructures, explosive processes, catalytic reactions, and biological objects. The results of these experiments are applied both to the fundamental research and to technology. Nuclear physics experiments on an inner gas target are also going on. An inner gas target is a high-intensity jet of gas (hydrogen or deuterium), injected directly into the vacuum chamber of the VEPP-3 storage ring. Controlling the polarization of the atoms of the target gas and analyzing the scattering of electron beam on the target, one can obtain unique information about the structure and properties of the proton. Currently, such experiments cannot be conducted on any other cyclic accelerator in the world.
