A non-destructive beam spatial profile monitor system using a gas sheet has been developed. The 4 mm thick gas sheet of over 40 mm width enables increase of the local gas pressure high enough to record a two-dimensional beam profile. A CCD camera coupled to an image intensifier detects photons produced by beam-gas interaction with the signal intensity that makes the time evolution study of the beam possible. We demonstrated that the J-PARC 3MeV, 60 mA H - beam profile which is measured with intensity error of 8.4-12% and spatial resolution of 1 mm changed depending on the controls of the acceleration cavity in the beam pules of 50 μ s.
