DESCRIPTION:Speakers: Alexandr Kozhukhov ()\nA prototype of a matrix pixel
  detector based on LYSO scintillators with EQR15-3030 type silicon photomu
 ltipliers [1] has been developed\, and studies of its characteristics have
  been carried out. The dimensions of the detector’s scintillation elemen
 ts are 3×3×20 mm\; the time resolution is 150 ps\, and the energy resolu
 tion is about 15% for gamma ray photon energy of 511 keV. \nThe coordinate
  coding scheme is based on the “active matrix” principle\, which impro
 ves the signal-to-noise ratio during reading and significantly increases t
 he slew rate of the output signal from the matrix\, thereby improving the 
 detector’s temporal resolution. Time parameters are measured using a mul
 tichannel TDC based on an FPGA [2]. The report will present a description 
 of the detector\, its electronics\, and the results of characteristic meas
 urements.\nReferences\n1. Measurement of Time Resolution of Scintillation
