DESCRIPTION:Speakers: Boris Tolochko (Institute of solid state chemistry a
 nd mechanochemistry)\nNow we are preparing an experiment to study the beha
 vior of the crystal lattice of the material of the fusion reactor first wa
 ll in a plasma discharge on the diverter. A fast one-coordinate X-ray dete
 ctor was developed for this experiment. The detector enables fast recordin
 g of 100 diffraction frames with an exposure time of 73 ps and a periodici
 ty of 100 ns. Thus\, we can record X-ray "movies" with high time resolutio
 n\, which store information about the dynamics of plasma interaction with 
 the structure of the crystal surface in a plasma discharge (100 μs in the
  ITER). To solve this problem we are developing an installation to work on
  beams of synchrotron radiation of VEPP4(BINP SB RAS). The installation wi
 ll enable obtaining information about what is happening to the crystal lat
 tice when the plasma of the ITER reactor interacts with the wall for a sho
 rt period of time. The plasma discharge parameters in the ITER are as foll
 ows: an energy of 100 J for 100 μs on an area of 1 mm2. We conducted firs
 t successful test experiments\, having recorded changes in the crystal lat
 tice W\, using a laser with a power of 1 J and a pulse width of 100 μm. N
 ow diffraction patterns with a time resolution of 73 ps can be recorded.\n
