Monte Carlo Simulation of the Electromagnetic Calorimeter Work by GEANT4
R. V. Salianka

Experimental and theoretical studies of direct photon production in hadronic collisions essentially expand our insights about multiparticle production mechanisms. These photons are useful probes to investigate nuclear matter at all stages of the interaction. Soft photons (SP) play a particular role in these studies. A specific feature of the proposed photon detector is its capability to measure low energy deposit E_thresh ≤ 5 MeV. SP investigations are proposed to study at SVD-2 setup at U-70 accelerator, IHEP (Protvino, Russia), Nuclotron at JINR (Dubna, Russia) and at future collider NICA (JINR). For these purposes an electromagnetic calorimeter (ECal) is manufactured of BGO scintillators. The results of Monte Carlo simulation of ECal job for soft photon registration by using GEANT4 is presented.
