 Superconducting Magnets for SR Generation in Budker INP: the Status of Works 

  • N.A.Mezentsev
    Budker Institute of Nuclear Physics, Novosibirsk, Russia

The synchrotron radiation (SR) user’s community in their requirements moves ahead to more rigid SR spectrum and to higher photon flux density. Performance of these requirements on SR sources with electron energy of 1-3 GeV is carried out by simple and cheap enough way – installation of superconducting shifters and multipole wigglers with high magnetic field. Besides there is an opportunity of replacement of normal conducting bending magnets on superconducting ones with magnetic field up to 8.5 Tesla, that essentially expands spectral range of radiation. Parameters of the superconducting magnetic systems made in Budker INP for the SR centers in the world are resulted. Consumer SR properties from these devices are discussed.

    Synchrotron radiation (SR) with relatively hard spectrum (up to 50 keV) is necessary for realization of number modern X-ray analytical methods. These methods can be effectively used in industrial and medical applications, in universities and scientific centers. So, the task of developing of compact source of hard synchrotron radiation is still actual. Budker INP has a big experience for developing and fabrication of high field superconducting insertion devices for different SR centers. In frame of this activity a superconducting bending magnet with field up to 9.6 T was fabricated for BESSY-II and commissioned in 2004. This magnet also became a prototype for compact hard SR source. A project of such storage ring is under developing in Budker INP now. This design fixed beam energy to 1.2 GeV, ring circumference about 52 m. Estimated horizontal equilibrium emittance will be near 20 nm. This report includes a detailed description of main parameters and magnetic structure of designed storage ring as well as preliminary design of injector system and beamline layout.

Electron-positron collider VEPP-2000 with beam energy up to 1 GeV is under commissioning at Budker Institute. This paper presents magnetic elements of the storage ring including 13T focusing superconducting solenoids in interaction regions. Features of magnet elements design and magnetic measurements results are given together with comparison to previously calculated data.

At present the dedicated synchrotron radiation source Siberia-2 in Kurchatov Institute operates with electron energy 2.5 GeV and current up to 200 mA. In order to expand spectral range of SR and to increase brightness an installation of 7.5 T 19-pole superconducting wiggler is planned at the end of 2006. Now the wiggler is under fabrication in BINP, Novosibirsk. Such high level of a magnetic field in the wiggler will have a great influence on electron beam parameters of Siberia-2. Changes of these parameters (betatron tunes, horizontal emittance of the electron beam, momentum compaction, energy spread etc.) are discussed in the report. Different methods of compensation (global and local) of betatron functions distortion are presented. Much attention is paid to dynamic aperture calculations using analytical approximation of magnetic field behavior in transverse horizontal direction.

3.5 Tesla 49-pole superconducting wiggler with 16 mm magnetic gap and 60 mm period for Diamond Light Source (England) has been fabricated in Budker INP. A first wiggler test was carried out in bath cryostat in BINP on July 2005. The first wiggler test in own cryostat was performed in BINP on January 2006. This test includes field integrals measurements with stretched wire method and field measurements with hall probe. All this measurements was repeated on April 2006 in DLS. Design of special magnetic measurement system with anti-chamber and main wiggler tests results are presented in this paper.

    Applications of synchrotron radiation (SR) are very popular for last time in many research fields. Thus a developing of compact source for generation of hard X-ray synchrotron radiation is very actual task. The goal of this work is a developing project of SR source for Republic of Kazakhstan. This storage ring mainly dedicated for performing the high sensitive X-ray fluorescence analysis of different natural samples to be used for ore exploration, ore processing and metallurgy . But implementations of other popular techniques applied for research and education with using synchrotron radiation (XAFS, XRD, etc) are also possible.
