DESCRIPTION:Speakers: Maxim Kheymits (NRNU MEPhI)\nA new method of high-en
 ergy gamma ray incident direction reconstruction is\ndeveloped for gamma-r
 ay detectors with multilayered converters. The method uses\ndata from conv
 erter and\, if available\, from position-sensitive calorimeter to\nreconst
 ruct an electromagnetic cascade axis and to determine the incident directi
 on\nof a primary gamma. For the first time to find point of intersection o
 f gamma\ndirection line with a convertor plane\, the median of energy depo
 sit in sensitive\nplane of a convertor is used. Applied\, for example\, to
  space gamma-telescope “GAMMA-400” this method allowed to achieve the 
 angular resolution ~ 0.01° at gamma-ray energy of 100 GeV\, being much 
 better than accuracy of the past and present space-\nand ground-based expe
 riments. In the algorithm presented\, a trade-off between the\nangular res
 olution and the effective area can be found to meet scientific goal of an\
 nexperiment.\n\nhttps://indico.particle.mephi.ru/event/22/contributions/11
