【 摘 要 】

Response function simulation using Geant 4 for the detector based on NaI crystal of complex shape in registration systems for the SAGE and BEST experiments is presented. Cylindric NaI crystal has a large well for placing up to eight proportional counters. The detector is using as anti-coincidence shield for counters and an instrument for analysis of different γ-rays sources. The result of detector response function simulation for different background sources and their registration efficiency are given.
