DESCRIPTION:Speakers: Ahmed cherif Chergui ( National Research Nuclear Uni
 versity (MEPHI))\nThe modern trend in developing of the transmission x-ray
  scanners based on fast scintillators and SiPMs arrays combining gamma pul
 ses counting and amplitude selection methods. Such scanners can be very at
 tractive for medical imaging and human/luggage inspection. These applicati
 ons require commercially available\, cheap scintillators with high brightn
 ess\, high density\, good linearity and energy resolution. Additional impo
 rtant requirements are fast decay time and a low contribution from an afte
 rglow. A one possible candidate for such application is interesting new sc
 intillator material Gadolinium Aluminium Gallium Garnet doped by Ce–GAGG
  (Ce) crystals. The comparative study of several different GAGG(Ce) crysta
 ls from Japan C&A Corporation and Russian firm Fomos Materials have been t
 ested with different photosensors and their linearity\, energy resolution 
 and photokinetics have been measured. The requirements for selection of th
 e best crystals for X-ray transmission scanners will be formulated and res
 ults presented.\n\nhttps://indico.particle.mephi.ru/event/35/contributions
