To diagnostic property of the proton beam introduced to the target, a multi-wire profile monitor (MWPM) was utilized, by which one -dimensional profile can be obtained. Since the nonlinear optics is employed to decrease peak current density at the target, two-dimensional information is required. To obtain a two-dimensional profile, we have been developing a new profile monitor based on the luminescence material. Since degradation of luminescence is concerned, which is observed at the SNS monitor system, an experiment was performed by using Al2O3 doped Cr material irradiated with Ar ion beam having the energy of 150 MeV at cyclotron facility in TIARA. During irradiation, degradation of the light yield of luminance was observed. For the development of the monitor less degradation of luminescence, other materials such as Y2O3 irradiation is planned.
