The new project of 4th generation synchrotron light source called Ultimate Source of Synchrotron Radiation (USSR) today is under development at NRC Kurchatov Institute. A number of Russian institutions also take part in this project: NRNU MEPhI, NRC "Kurchatov Institute" - ITEP and others. The European Synchrotron Radiation Facility (ESRF, Grenoble, France) is the main international collaborator of the project. It is proposed that USSR include both a storage ring and soft FEL, and one linac will be used for injection in the storage ring and as a driver for the FEL. The preliminary design of 6 GeV storage ring with transverse emittance of 50-70 pm*rad is done. The general concept of the top-up linac is proposed and the beam dynamics is simulated. The injection system and the vacuum systems are studied. Current results of the USSR R&D will be presented in this report.

  The Kurchatov synchrotron radiation source goes on to operate in the range of synchrotron radiation from VUV up to hard X-ray. An electron current achieved 200 mA at 2.5 GeV, up to 12 experimental stations may function simultaneously. An improvement of an injection process allowed to minimize injection time and to increase injection efficiency. A production of two new superconducting wigglers is now in progress in BINP (Novosibirsk). They will be installed on the main ring in next year. Great modernization of the whole facility is planned for 2020. The present status and future plans of the Kurchatov synchrotron radiation source is presented in the report.

Siberian Circular Photons Source "SKIF". Project review.  
 
  • K. Zolotarev

  The main problem of the Siberian Synchrotron and Terahertz Radiation Center (SSTRC) is absence of the modern light source. In spite of intensive exploring of SR beams and SR analytic techniques of the SSTRC by a large number of user groups, the SR parameters of the currently used beams strongly restrict capability of the used techniques. Budker INP has rich experience and technologies for developing and building complex accelerator facilities. Moreover, the unique scientific environment of the SSTRC provides a high demand for modern light source in the Novosibirsk Scientific Center only. Thus, the creation of the new light source is highly relevant issue. After analysis of the user requirements and modern accelerator approaches for design of magnetic lattice for high brightness light source the Budker team proposed an option of the magnetic structure of a new light source for Novosibirsk Scientific Center. The project was named "SKIF". Current report describes the main parameters for the proposed light source as well as common design of the accelerator complex, magnetic structure of the main ring and buster accelerator. The preliminary scedule and systems cost analysis are included.

TUPSA16 Computer Codes for Calculation of Electromagnetic Radiation Generated in Magnetic Fields 181
 
  • N.V. Smolyakov, R. G. Chumakov
    NRC, Moscow, Russia
 
  Software for simulation of different characteristic of spontaneous electromagnetic radiation, generated by a relativistic electron beam in external magnetic field, is presented. It consists of several different computer codes, which are in consistent with each other. Computer codes calculate spatial and spectral distributions of electromagnetic radiation intensities. Explicit expressions are used for the emitted electric field components, including the so-called velocity term. The codes simulate the electron trajectory in the external magnetic field numerically, by using the experimentally measured values of the field. The real geometry is used for the simulation. For example, the near-field effects are taken into account. The electron beam emittance is simulated by numerical convolution of the Gaussian electron distribution in a beam with the spatial distribution of the electromagnetic radiation, generated by one electron. As an example, the edge radiation, generated at the ends of bending magnets of the Siberia-2 storage ring, is considered. Calculations show that the edge radiation intensity must significantly exceed the intensity of standard synchrotron radiation, formed by the homogeneous field of a bending magnet, in the infrared and ultraviolet spectral regions. This set of computer codes will also find wide application in the new project of the fourth generation of a specialized synchrotron radiation source ISSI-4.

Modern project of 4th generation synchrotron light source USSR (Ultimate Source of Synchrotron Radiation) is under consideration now in Russia. A FEL is considered as a part of USSR complex. For this reason top-up linac is discussed as the main injector. Nevertheless, other injection schemes should be studied too and two variants of the booster ring are proposed. On the one hand the booster ring can be placed together with the main storage ring in common tunnel similarly to Sirius, TPS and SLS. In this case its circumference will be close to 1300 m. Alternately, compact (~ 300 m) booster ring is also under investigation. Current status of the development of two booster variants and preliminarily results of the electron dynamics simulation are presented.

It was proposed that USSR will include both storage ring and soft FEL and one linac will used for injection in synchrotron and as a driver for FEL. The general concept of the top-up linac is proposed and the beam dynamics was simulated. It is suggested to use two RF-guns in this linac similar to Super-KEKB, MAX-IV and CERN FCC. One of the RF-guns should be classical with thermionic cathode and will be used for injection. The second one having photogun will use to generate a bunch train (for FEL. Current results of the top-up linac general scheme development and first results of the beam dynamics simulation will present.

WEPSB28 Em Fields in a Metal in an External Magnetic Field at Low Temperatures 340
 
  • V.I. Moiseev, V. Korchuganov
    NRC, Moscow, Russia
 
  Radio waves do not penetrate deep into the metal due to the high density of charge carriers in the metal. In the shorter-wave part of the spectrum, metals can be "transparent" only starting from ultraviolet, since the plasma frequencies in metals lie in the ultraviolet range. However, for a metal cooled to a low temperature and placed in an external magnetic field, the situation may change. Under these conditions, cyclotron orbits can be formed, and the relaxation time can significantly exceed the period of cyclotron motion of the charge carriers. For an electromagnetic wave with polarization normal to the induction vector of an external magnetic field, the exchange of energy with charge carriers in the metal turns out to be suppressed. Such a wave can propagate in the metal for relatively large distances (in comparison with the skin layer). In this connection, in electron storage rings at the azimuths, for example, of superconducting strong-field wigglers, with the magnetic field rise, the effect in the surface impedance change of the wiggler vacuum chamber metal can be manifested. This report is a brief review of some of results known in solid state physics applicable to these conditions and of interest to accelerator technology.

The new 4th generation synchrotron light source USSR (Ultimate Source of Synchrotron Radiation) is under development at National Research Center "Kurchatov Institute" now. The full-scale 6 GeV storage ring is considered as the main part of USSR light source. Beam dynamics simulations shows that this ring, with 7BA magnet lattice, can provide the horizontal beam emittance close to (50-70) pm*rad. Currently, circumference of storage ring is about 1300 m because of considering magnets without combined functions. The general concept of the storage ring, its magnetic lattice and first beam dynamics simulation results will be discussed.

  The multipole superconducting wiggler was designed, fabricated and successfully installed and tested on DELTA Synchrotron Radiation Source. The wiggler represents a multipole magnet with alternating high magnetic field of 7 Tesla along movement of particles in storage ring. The magnet is immersed into liquid helium of a special cryostat with working temperature of ~4.2K. The wiggler consists of 22 pairs of poles superconducting magnet with 18 full field poles, 2 with a three-quarter field strength and 2 with one-quarter field poles. The magnet array produces a sin-like magnetic field variation on the magnetic axis of the device with first and second field integrals close to zero. The Dortmund Electron Accelerator (DELTA, Germany) operated at 1.5 GeV synchrotron radiation source requires a superconducting wiggler as an insertion device for three x-ray beamlines with photon energies up to more than 30 keV. The wiggler has a period of 127 mm, magnetic field of 7 Tesla and the length from flange to flange of 2.2 m operated with zero boil-off mode. The conception and main approaches for the design of the magnetic and cryogenic system as well as the main parameters and the test results of new 7 Tesla superconducting wiggler for DELTA synchrotron light source are presented.
