Plasma-Surface Interactions and Plasma Technologies Laboratory

The lead scientist is Sergey I. Krasheninnikov (Doctor of Physico-Mathematical Sciences [Dr. Sci. (Phys.-Math)], Honorary Professor of University of California, San Diego, Professor of MEPhI)

The purpose of the project:
Solving both the applied and fundamental current problems of interaction between plasma and surface, as well as development of the new plasma technologies based on interaction between plasma and surface.

The expected results of the project:

  • Development of new models and computer codes for describing of how the hydrogen isotopes leave the materials of thermonuclear reactor, together with describing of abnormal effects experimentally observed in tokamaks and laboratory facilities;
  • Development of models and computer codes for describing of material erosion, transport of neutral and ionized impurities and dust in the multicomponent peripheral plasma in tokamaks and model facilities;
  • Modernization of several facilities for studying of interaction between plasma ions and surface, such as ion mass separator, thermal desorption rig, films and hydrogen co-deposition facility;
  • Modernization of the existing technical facilities and designing of the new ones for studying of coating and material surface modification, including the facility with abnormal glow discharge, the facility with high-frequency discharge, the pulse magnetron facility, the facility for sputtering materials from a liquid phase;
  • Solving new objectives associated with the development of elements and super-capacitors, including current collectors and electrodes, is anticipated. The main purpose is to increase capacity and decrease resistance of super-capacitors.

Conducting of the experimental research in the field of gas discharge physics:

  • on oxidation in the plasma of nano-structured surfaces with large area in application to creation of anode foils for high capacity electrolytic capacitors;
  • on nitriding and blackening of steels and titanium alloys in the plasma of abnormally glow and high-frequency discharges in application to the problem of increasing the strength and reducing wear of machine and mechanism parts;
  • on tube discharges and modification of tube inner surface using abnormal glow discharge;
  • on modes of magnetron discharge with liquid cathode and on specific features of coatings made in such discharge in application to the problem of high-speed coating by sputtering methods.
