Ushkov Russian Research Centre Kurchatov Institute, Moscow, Russia Abstract The accelerator complex of the KCSR consists of 2.5 GeV main storage ring, 450 MeV booster storage ring and 80 MeV linac. A project of the complex modernization comprising new brighter optical lattices of main storage ring and new injection system were developed in KCSR. New optical lattices will allow to reduce natural beam emittance from present 100 nm∙rad to 18 nm∙rad. But due to significant decrease of dynamic aperture the efficiency of injection from the booster storage ring having big natural emittance will be drastically reduced. A new 2.5 GeV booster synchrotron (BS) with 50 nm∙rad emittance was developed to overcome this problems. It will be placed in the same tunnel with main ring. Modernization project provides for a possibility to increase injection energy from linac to BS from 80 MeV to 160 MeV by double electron bunches transition through linac structure. ª – corresponding author |

Tsukanov² ¹Russian Research Centre Kurchatov Institute, Moscow, Russia ²Budker Institute of Nuclear Physics Siberian Branch of the Russian Academy of Sciences, Novosibirsk, Russia Abstract 7.5 T 19-pole superconducting wiggler has been installed on SIBERIA-2 storage ring in December 2007. First results of an operation of Siberia-2 with the wiggler are described. An influence of the wiggler on betatron tunes, closed orbit, betatron functions and other beam parameters is discussed. Calculated and measured influence on beam parameters is compared. ª – corresponding author |

Ushkov, A. Valentinov, A. Vernov, Yu. Yupinov, A. Zabelin Russian Research Centre Kurchatov Institute, Moscow, Russia Abstract Kurchatov Synchrotron Radiation Source (KSRS) works for the experiments in the range of SR from VUV up to hard X-ray. Recently a project of technical modernization of KSRS was carried out. It consists of 3 parts: the enlargement of useful experimental hall surface by means of the new building; upgrade of accelerator facilities and injection scheme to improve the SR complex capabilities; construction of new beam lines and experimental stations around Siberia-2 facility. The building was started from the end of 2007. The technical upgrade of SR complex will start in 2009. The report describes the current work and plans at accelerator facilities. The achieved consumer parameters of an electron beam are given. ª – corresponding author |
