DESCRIPTION:Speakers: Mihail Fedotov (BINP)\nSome matrix detectors (CCD an
 d CIS) have direct X-ray sensitivity and can operate as dispersionless spe
 ctrometers with a very large number of elements (10E6 and more). In the ca
 se of the impulse diffraction such detector can simultaneously record a si
 gnificant number of independent events. In the reading the position and en
 ergy of the absorbed X-ray photon may be restored for each event. The math
 ematical processing of the received data with respect to the Bragg conditi
 on can theoretically lead to the coordinates of the events of one fixed en
 ergy and to form an analogue of powder diffraction patterns. In this case 
 the registration can be performed on the "white" SR beam for a short time 
 (up to 1 ns or less). \n     \nThe possibility of using of the 2000-elemen
 t linear CCD ILX511 (Sony) as X-ray dispersionless spectrometer allowed to
  conduct simulation experiments to obtain diffraction patterns of graphite
 \, boron nitride and TNT-hexogen solid detonation products. SR beam was mo
 dulated by a mechanical chopper and statistics were provided by a multiple
  recording with on-line processing.\n\nhttps://indico.inp.nsk.su/event/3/c
