Research Abstract	We investigated future experiments to test interaction models using nuclear collisions at the CERN LHC accelerator. In point of view of the model discrimination, particle multiplicity and radiation dose, we concluded that we can perform a crucial experiment at Nitrogen collisions, but not at the Lead collisions assuming to use the current LHCf detector. We also studied the basic properties of GSO crystal scintillator to reduce the radiation damage. We concluded that the GSO scintillators are radiation hard enough and have satisfactory properties compared with the plastic scintillators used in the current detector.
