We present design and characteristics of prototype of electromagnetic calorimeter (EmCal) for the Electron-Ion Collider (EIC) which was designed and built in A.I. Alikhanyan National Science Laboratory (AANL). Electromagnetic Calorimeter (EmCal) based on lead tungstate (PbWO4) crystals is proposed to be a key element of particle identification system of EIC. A prototype of EmCal was designed, constructed and tested with cosmic muons. It consists of 16 PbWO4 crystals arranged in a 4×4 matrix. The results confirm conclusions of other groups in the EIC collaboration that the quality of crystals produced by CRYTUR meets requirements for EmCal of EIC.
