A. Anoshinª, E. Fomin, V. Korchuganov, Yu. Krylov, V. Kvardakov, S. Pesterev, S. Tomin, V. 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 |

ELECTRON BEAM DYNAMICS IN LINAC OF KURCHATOV SOURCE OF SYNCHROTRON RADIATION WITH ENERGY DOUBLING |
|

A. Anoshin, E. Fominª, V. Korchuganov, S. Tomin Russian Research Centre Kurchatov Institute, Moscow, Russia Abstract According to new injection scheme projected for the Kurchatov synchrotron radiation source a full energy booster synchrotron is planed to be the injector of the main storage ring SIBERIA-2. An existing linear accelerator will simultaneously serve as 80 MeV injector for storage ring SIBERIA-1 and as injector for the booster synchrotron with the electron energy of 160 MeV. The energy doubling scheme will be realized by magnetic mirror at the end of linac structure and second passage of electrons through accelerator structure of the linac. This paper describes the possibility of electron energy doubling. The results of computer simulation of electron beam dynamics during the double passage linac structure are presented. 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 |

A. Anoshin, E. Fomin, V. Korchuganov, S. Tominª Russian Research Centre Kurchatov Institute, Moscow, Russia Abstract The creation of the diffraction limited radiation source (DLS) on the base of an in – vacuum mini-undulator with wavelength 6 Å is considered at a storage ring SIBERIA-2. Main parameters of undulator as a DLS are defined. Spectral characteristics of undulator radiation taking into account the electron beam parameters are obtained. In addition method and possibility to obtain the minimal electron beam emittance in SIBERIA-2 storage ring, influence of insertion device (ID) on emittance, energy spread, linear and nonlinear motion of electron beam and dynamic aperture are the subjects of studying. ª – corresponding author |
