DESCRIPTION:Speakers: Yury Trofimov (National Research Nuclear University 
 MEPHI)\nGRIS (Gamma and Roentgen radiation of the Sun) is a prospective ha
 rd X-ray and gamma-ray spectrometer of solar flares with the energy range 
 from 50 keV to 200 MeV. It is also designed for registration of high energ
 y neutron fluxes (>30 MeV). The apparatus will be mounted on an oriented p
 latform outside the Russian Orbital Segment of the International Space Sta
 tion. The instrument includes two detector heads: a low energy spectromete
 r (LES) based on a fast scintillator with relatively high energy resolutio
 n 3.5–4.5% at 662 keV (LaBr3(Ce) or CeBr3) and size of ø7.62×7.62 cm\,
  and a high energy spectrometer (HES) based on ø12×15 cm CsI(Tl) scintil
 lator. Thanks to n/γ discrimination capability of CsI(Tl) crystals\, the 
 HES spectrometer is also intended for neutron registration. \nTo estimate 
 GRIS instrument registration capabilities\, simulation of the HES neutron 
 and gamma registration channels response to background radiation and to so
 lar flares of different magnitude and spectral compositions was performed.
  Expected spectral and n/γ discrimination performances based on measureme
 nts with detectors prototypes are represented.\n\nhttps://indico.particle.
