DESCRIPTION:Speakers: Ekaterina Mosolova (Joint Institute for Nuclear Rese
 arch/Peter the Great St. Petersburg Polytechnic University)\nUsing the Mon
 te Carlo method (GEANT4)\, energy deposit distributions were obtained for 
 incident gamma photons with energy from $256$ MeV up to $8192$ MeV interac
 ting with the various parts of the spaghetti calorimeter (SPACAL). The SPA
 CAL consists of nine scintillation single crystal gallium-gadolinium garne
 t (GGG) rods with dimensions $3\\times3\\times100$ $\\text{mm}^3$ forming 
 a $3\\times3$ array surrounded by tungsten. The distribution of energy dep
 osit on the boundary of the connection and in the crosshairs of cells were
  also considered. Distributions were obtained for the central crystal\, th
 e ring of eight crystals surrounding the central crystal\, and over all th
 e crystals.\n\nAs a result\, the amount of energy that remains in the crys
 tal surrounded by tungsten equal to $34\\%$ of the energy released in a pu
 re GGG scintillator when a photons hit the crystal. Released energy in pho
 ton tungsten interaction lies in range from $1.65\\%$ to $4.5\\%$ and depe
 nds on incident point position.\n\nThe high light yield of GGG crystal $3\
 \times3$ array detector allows for performing measurements in nuclotron-ba
 sed ion collider facility (NICA) experiments at the Joint Institute for Nu
 clear Research (JINR).\n\nhttps://indico.particle.mephi.ru/event/22/contri
