DESCRIPTION:Speakers: Vladislav Alekseev (P. G. Demidov Yaroslavl State Un
 iversity)\nThe sampling imaging electromagnetic calorimeter of $\\approx 1
 6.3$ radiation lengths and $\\approx 0.6$ nuclear interaction length desig
 ned and constructed by the PAMELA collaboration as a part of the large mag
 netic spectrometer PAMELA. Calorimeter consists of 44 single-sided silicon
  sensor planes interleaved with 22 plates of tungsten absorber (thickness 
 of each tungsten layer 0.26 cm). Silicon planes are composed of a $3\\time
 s3$ matrix of silicon detectors\, each segmented into 32 read-out strips w
 ith a pitch of 2.4 mm. The orientation of the strips of two consecutive la
 yers is orthogonal and therefore provides two-dimensional spatial informat
 ion. Due to the high granularity\, the development of hadronic showers can
  be study with a good precision.\n\nIn this work a Monte Carlo simulations
  (based on Geant4) performed using different available models\, and includ
 ing detector and physics effects\, compared with the experimental data obt
 ained on the near Earth orbit. The response of the PAMELA calorimeter to h
 adronic showers investigated including shower radius\, longitudinal and tr
 ansverse shower profiles etc.\n\nhttps://indico.particle.mephi.ru/event/4/
