Abstract：
Using a large-scale iron emulsion chamber,a big γ-ray family event with observed energy ΣE_γ=7631TeV was obtained.This paper described the advantages of iron emulsion chamber for studying big families and the characteristics of the event observed,together with a comparison with the Monte-carlo simulation results.
