Fourth Generation Special-purpose Synchrotron Radiation Source



The SSRS-4 project is designed to construct a brand new dedicated source of x-ray radiation – a source of synchrotron radiation of the 4th generation with three main characteristics: extremely high spatial coherence (corresponding to laser radiation), record brightness and temporal structure. It is expected that such facility will allow to carry out fundamental and applied research which may lead to breakthroughs in the fields of condensed matter physics, nano- and biosystems, including hybrid systems, functional and biocompatible materials, medical diagnostic systems and targeted drug delivery and also to the innovation process in the fields of superconductivity, magnetic systems, materials science, instrument engineering.

Under construction: since 2017

Commissioning: 2027


National Research Centre “Kurchatov Institute”


Photon science





The machine should comply with all main demands of x-ray scientific community, so that its beamlines have to implement all main x-ray techniques in the area of x-ray diffraction, spectroscopy and imaging. As the machine will produce highly coherent beam, the most advanced beamlines will be dedicated to phase contrast imaging, photon correlation spectroscopy and nanofocused x-ray beams.





The SSRS-4 facility should become an interdisciplinary shared use center of the world level. Main scientific fields to be addressed to are following:

  • investigation of the structure and dynamics of living and inanimate matter with atomic spatial and femtosecond time resolution;
  • development of new technologies for synthesis and diagnostics of nanostructured and hybrid materials;
  • studying the features of molecular biological and neurophysiological processes in living systems;
  • new material search for ultrafast computers, including those basing on artificial intelligence, the development of new approaches to study brain functions and the genetic apparatus;
  • creation of new drugs and methods for their targeted delivery, the development of x-ray medical nanodiagnostics and nanotherapy methods; 
  • studying the fine features of the structure of macromolecular crystals, biological cells and membranes, including their structural dynamics;
  • synthesis of materials with new crystalline and magnetic properties;
  • studying phase transitions under conditions close to the conditions in the center of the Earth and other planets;
  • generation and analysis of plasma states and the stability of structural materials for the development of new types of thermonuclear facilities;
  • increase by several orders of spatial and temporal resolution in the study of the structure of nanoobjects and nanomaterials up to single molecules.
