The modernization project of the vacuum system of the synchrotron radiation source at the National Research Centre Kurchatov Institute (NRC KI) has been designed and is being implemented; it includes a change in the system to high-voltage power sources for NMD and PVIG-0.25/630 pumps. The system is controlled via the CAN bus, and the vacuum is controlled by measuring pump currents in a range of 0.0001–10 mA. The system ensures a vacuum of 10 −7 Pa. The status is mapped and the data collected into the archive are processed on the MS SQL Server platform. The efficiency and reliability of the vacuum system is increased by this work, making it possible to improve the main parameters of the SR source.

In 2006, the work was continued at the linear accelerator-injector of TNK facility, Zelenograd. In November-December, the linear accelerator conditioning was carried out to increase the output electron energy. The accelerated electron beam was obtained at the Faraday's cup located in the plane which was equivalent to the booster ring entrance point. The paper presents the accelerating structure conditioning results and diagrams of the beam pulse shape at the accelerator output and energy spectrum at the booster ring input.

Industrial storage facility at Lukin State Research Institute for Problems in Physics, Zelenograd includes two electron storage rings: the main ring for energy of 2.5 GeV and booster ring for energy of 450 MeV. Linear accelerator for electron energy up to 80 MeV serves as an electron injector of TNK facility. The accelerator was commissioned in December, 2002. The accelerated current of similar to 50 mA at 55 MeV was obtained. The paper presents the linear accelerator scheme and time diagram for its parts operation. DAW accelerating structure and beam transportation channel to the booster ring are described. The electron beam parameters obtained are listed.

An ionizing detector for on-line registration and representation of the geometric SR beam parameters was developed in RRC KI. The detector analyses the products of the residual gas ionization, which was done by the investigated beam. Special electrostatic optics and open image converter tube (ICT) form optical image of the real beam on the screen of ICT. The detector was checked on SR beams of the next storage rings: DCI (LURE, Orsey, France), KSRS (RRC KI, Moscow, Russia) and MAX-2 (MAX-lab, Lund, Sweden). The codes for TV image processing give a possibility for numeric estimation of the beam size, the width of its horizontal and vertical profiles and position of the beam gravity. Statistic processing of the beam gravity center using big amount of TV frames gives uncertainty in the beam position of about 2μm while the width of the beam is about 2mm. Summation of big amount of TV frames was used. This method significantly increases signal-to-noise ratio.

A Deep X-ray Lithography (DXRL) beamline at the Kurchatov Synchrotron Radiation Source (KSRS) has been constructed and commissioned. For the irradiation a simple exposure apparatus and synchrotron radiation with a critical energy of about 7 keV was used. Samples with resist thickness of 300 μm and 500 μm have been exposed using a test mask. SEM results are shown.

The ionizing Beam Cross-section Image Detector (BCID) is developed. The detector can measure the shape, the size and the profile, the position and angle of a SR beam without any influence on it. BCID is installed into separate vacuum chamber with Be windows. For better sensitivity the chamber is filled with Ar or Xe under the pressure about 10 -3 10 Torr. The detector was checked on SR beams of the next storage rings: DCI (LURE, Orsay, France), KSRS (RRC KI, Moscow, Russia) and MAX-2 (MAX-lab, Lund, Sweden). All these experiments showed high sensitivity and good resolution of the detector and clear images of the beam cross-section. Summation of big amount of TV frames was used. This method increases signal to noise ratio. Resulting image is saved in computer for further processing. Uncertainty of some microns was achieved for SR beam gravity center while the size of the beam was about two millimeters. The results achieved can be used for registration of ionizing beams on accelerators of different types.

This paper reviews the status of the SIBERIA storage rings complex. The parameters of the linac, booster synchrotron and main ring are given. The transfer of the SIBERIA-1 storage ring to its new site is described. The main parameters of the engineering systems for the SIBERIA complex are presented. The assembly of the SIBERIA-2 storage ring is planned to be finished in 1991.The SIBERIA storage rings complex has been constructed at the Kurchatov Institute for Atomic Energy (IAE) and is the first dedicated synchrotron radiation source in the USSR. The facility includes the SIBERIA-1 450 MeV electron storage ring, the SIBERIA-2 2.5 GeV electron storage ring, two electron transport lines EOC-1 and EOC-2, and an 80-100 MeV electron linac which serves as the injector. The general layout of SIBERIA is shown in fig. 1. All accelerators of the SIBERIA facility are designed and manufactured at the Institute of Nuclear Physics (INP) at Novosibirsk.

The station for solid-state VUV spectroscopy on the dedicated SR source Siberia-1 of the Kurchatov Institute, USSR, is described. The station consists of a beam line, a Seya-Namioka monochromator with toroidal focusing mirrors, a high-vacuum sample chamber and a computer control system. Characteristics of the optical scheme are discussed.

The report deals with the results of developing the 450-MeV electron storage ring SIBERIA-1, i.e. the first phase of the specialized synchrotron radiation source of the I.V. Kurchatov Institute of Atomic Energy. The storage ring was designed, manufactured and put into operation by the staff of the Institute of Nuclear Physics of the Siberian Department of the USSR Academy of Sciences in 1983. In 1984 a superconducting “snake” with a 4.3 T field was mounted in the storage ring.
