DESCRIPTION:Speakers: Evgeny Postnikov (SINP MSU)\nThe mass composition of
  cosmic rays in the hundreds of TeV energy range is purely measured and un
 certain\, because   primary cosmic rays measurements on satellites require
 s a large area of detectors\, but energy is too low for application of  me
 thods developed for EAS measurements.  In this paper we  consider a possib
 ility to use the hybrid method originally aimed to   gamma hadron separati
 on in TAIGA experimrnt\,   to distinguish the diffrent mass groups among c
 osmic rays in the energy range 100 TeV- 500 TeV.  The international gamma-
 observatory TAIGA (Tunka Advanced Instrument for cosmic rays and Gamma-Ast
 ronomy) is intended for ultra high energy gamma-ray astronomy (>30 TeV). I
 t aims at combining the cost-effective timing-array technique with IACTs\,
  allowing to reach a total area up to a few square kilometers and strong s
 uppressing hadron background because of a very precise angular resolution 
 (order of 0.1 degrees at the energy >100 TeV). Hybrid operation of both of
  these techniques can lead to a relatively cheap way of development of a l
 arge area array. \n\nWe analyze Hillas’s  parameters of images produced 
 by different nuclei in IACT together with known arrival direction and show
 er core position\, measured by Hiscore timing arrays.  We show that hybrid
  method can be very effective for this task.\n\nhttps://indico.particle.me
